Gallant bid – Holder thrilled with Bravo, team effort despite defeat

first_img FALSE STROKES DUBAI, UAE (CMC): Captain Jason Holder has hailed Darren Bravo’s eighth Test century in difficult final day circumstances and said his entire team had showed plenty character, despite their 56-run defeat to Pakistan in the day/night opening Test here yesterday. Bravo stroked 116 at the Dubai International Stadium as West Indies, chasing 346 for victory, came up short on 289 in their second innings to fall 0-1 behind in the three-Test series. “It was a quality innings and he batted really well in both the first and second innings,” Holder told reporters afterwards. “I think he showed a lot of maturity in both those innings. He spent some time, he gave himself a really good chance to get a score and you could see the determination on his face and in his expressions and even his body language I thought it was very, very positive. “Hopefully we can continue in this vein and keep Darren Bravo leading our batting.” “That was obviously a crucial moment there. Bravo was the set batsman, he’d played beautifully up until that point, but it was tough coming out of the rough with Yasir Shah,” he explained. “I thought he bowled really well, he was very, very challenging and he made it difficult for us to score and also defend. “If you look back at it, you see a lot of things in hindsight, but obviously at the moment when Bravo got out we would’ve probably asked him to go on a little longer.” West Indies were always up against it once they conceded a lead of 222 on first innings after Pakistan had piled up a mammoth 579 for three declared in their first innings. However, with leg-spinner Devendra Bishoo taking eight for 49, the Windies bundled out Pakistan for 123 in their second innings to open up the game. Holder said the batting effort from his side in both innings and the bowling in the Pakistan second innings, was cause for encouragement. “I am obviously disappointed that we lost. At the end of the day it is still a loss, but having said that there are lots of positives I can take from this game,” he pointed out. “One thing is I am really proud of the guys for the way they fought. I must commend the guys, they stuck it straight through to the end, all the bowlers gave a really big effort on a pitch that didn’t give much assistance to them and I can’t really fault the effort of the guys. “I just think it was a very, very good team effort. Unfortunately we didn’t get over the line and unfortunately we didn’t save the game, but there are a hell of a lot of positives to take from this game.” Scoreboard PAKISTAN 1st Innings 579-3 decl.

CRUCIAL MOMENT Unbeaten on 26 at the start with West Indies on 95 for two, the left-hander survived the loss of veteran partner Marlon Samuels for four to the first ball of the day, to keep Pakistan at bay. All told, he faced 249 balls in a marathon 63/4 hours at the crease and struck 10 fours and a six. He anchored half-century stands with Roston Chase (35) and Jason Holder (40 not out), to carry West Indies’ victory bid late into the final session. However, with perhaps one of his few false strokes of the innings, he mistimed a drive back to Yasir Shah in the final hour to be seventh out at 263 and Holder said that dismissal was the turning point in the contest.last_img read more

Helpful Hacks for Researching With Older Adults

first_imgby, Christina Pierpaoli, ChangingAging ContributorTweet19Share24Share3Email46 SharesFor better or for worse, I hail from New Jersey—from a terrifyingly loud, frenetic Italian family no less. At risk of propagating stereotypes about my people, I should pause to admit a few things: (1) I speak quickly, (2) talk frequently, and (3) gesticulate wildly. And if we’ve ever talked at length, please know that my tendency to interrupt (I’m sorry) comes from nothing more than my benign inability to control the thoughts a-bubbling at the tip of my tongue.As a trainee of clinical psychology (working with older adults, no less) these tendencies sometimes present a few problems. Here’s why:Effective psychologists listen more than they speak. Also, interruptions frustrate people, compromise rapport, and contaminate process.Most clients, particularly older folks, struggle to process content delivered quickly or loudly.Indiscriminate gesturing distracts.Thankfully, I noticed these patterns very early in my training while reviewing session tapes, humbly digesting lessons from each of the seemingly thousands of blunders I committed. These lessons, beyond providing humbling fodder, invited me to evaluate my interactions with older folks in the lab, too.  To be sure, these tendencies have high costs both on the couch and in the lab, but may be uniquely expensive in experimental contexts where even small missteps can introduce error to the assessment situation.  And few assessment situations rival the delicateness of those with older adults.Classical test theoryAlbeit obvious, the point must be made: psychology is a science of constructs, not of tangibles like biology or geology.  And because psychologists cannot directly poke and prod the things they want to study—like anxiety, depression, dementia, intelligence—they attempt to tap these constructs psychometrically—using testing, measurement, and assessment.This approach, admittedly, has its flaws.  Classical test theory, sometimes known as true score theory (Allen et al., 2002), posits that a person’s observed score on any given assessment represents an additive composite of two components: a true score (error-free score) and an error score:X = T(true) + E(error)In more human terms, this means that the variability in measurement stems from the sum of variability due to true score and the variability due to error—or, error from the thing you’re actually measuring and how you are measuring it.Systematic error and random errorRandom and systematic errors characterize the two types of measurement errors.  Random errors describe statistical fluctuations in the data due to precision limitations of the measurement, resulting from the researcher’s inability to take the same measurement in exactly the same way to yield identical results. Random errors, unlike their systematic counterparts, typically stem from individual differences at the time of test taking—like level of arousal (i.e., anxiety), preparedness, or even physical health.Systematic errors, then, represent reproducible inaccuracies inherent to the system—divorced from the individual—due to problems persisting throughout measurement. In terms of psychological research, these errors might include poor wording of test items, the salience of stimuli, or even the validity of the constructs themselves.Sources of error to consider when testing older adultsSensory ImpairmentsConsidering the sensory, physical, and cognitive changes accompanying aging, making thoughtful modifications to the testing environment can help not only to optimize older adults’ performance, but also to reduce measurement error.“Typically, sensory acuity declines with age,” notes Sheila R. Black, Associate Professor of Psychology at the University of Alabama. “Keeping this in mind, researchers should anticipate that older adults will not be able to hear and see as well as younger adults,” she explains.To ignore this as researchers would be only at our peril. Dual sensory impairment (DSI)— only anticipated to spike as the population ages— refers to the presence of both hearing and vision loss. According to the Centers for Disease Control and Prevention, at least 1.7 million people report DSI, with between 9% and 21% of adults over 70 having some degree of it (Saunders & Echt, 2007).And presumably—if someone doesn’t have both visual and hearing impairments — (s)he likely has impairment in at least sight or hearing. Don’t buy it? Take that one out of six Americans over 70 has low vision due to common eye pathologies including macular degeneration and glaucoma (Elliott, McGwin, Kline, & Owsley, 2015) or that 59-76% have mid to high frequency clinical hearing loss, respectively (Helzner et al., 2005).Why does it matter? Because you can’t encode what you can’t sense.“Obviously, you want to make sure that your older participants can see and hear the stimuli,” says Kyle Kraemer, PhD student of cognitive psychology at the University of Alabama, “because otherwise, what are you really measuring?”But as others have pointed out, age related declines in sensory acuity may produce difficulties in performing cognitive tasks, even when visual or auditory stimuli presentation exceeds threshold levels that can be seen or heard (Baldwin & Ash, 2011).“Psychologists, both clinical and experimental, must therefore be sensitive to these differences across the lifespan, making adjustments in the lab or clinic when necessary,” emphasizes Black. “They also need to consider these changes when discussing experimental results.”Cognitive ImpairmentsThough sensory-acuity mediated performance provides another explanatory framework for age-related cognitive decline, another rests in widely accepted findings that prospective memory, episodic memory, and executive processing fade over time (Baldwin & Ash, 2011). Accordingly, some researchers have proposed that these age-related declines reflect impaired cognitive functions such as slowed information processing (Cerella, 1985; Salthouse, 1994) or decreased attentional capacity (Park et al., 2002, Salthouse, 1992).“I find that many older adults don’t like to participate in cognitive studies because the procedures often involve some sort of cognitive testing,” observes En Fu, PhD candidate of cognitive psychology at the University of Alabama. “Participants tend to recall how their cognitive capacity has declined, developing negative attitudes and feelings toward themselves that they may or many not bring to the study.”Tarek Amer, PhD student of psychology at the University of Toronto, echoes this: “I find it rewarding to work with older adults because they tend to be interested in my research questions,” he says, “but challenges include making sure that I am extremely careful with those who are concerned, sensitive, or anxious about their cognitive abilities,” he adds.And anxiety matters.Older adults, on average, harbor more negative beliefs and anxieties about their memory than younger adults. Most importantly, these anxieties actually appear to impair memory performance through the allocation of processing resources, strategy selection, motivation, or a combination of these factors (Chasteen et al., 2005).  Concerns about being negatively stereotyped impact performance too. Per Steele’s (1997) notion of stereotype threat, older adults performing in a situation in which negative stereotypes about aging and memory are activated show impaired memory performance (Chasteen et al., 2005).“Accordingly, I often reassure older adults that tasks are designed to challenge participants, and that it is very normal for participants of all age groups to find them difficult,” says Amer.He adds, “That said, the cognitive literature tends to focus on cognitive decline and how brain changes with age contribute to that decline. But many older adults are, in fact, major contributors to society and fully capable of performing tasks encountered in daily settings. My research focuses on how these cognitive changes can actually be beneficial in certain contexts, and I often share that.”Other health and physiological factors to consider: Circadian arousal & painTo complicate matters, individual differences in chronobiology also appear to influence experimental outcomes. Variation in circadian arousal correlates with performance on a variety tasks  (e.g. performing simple arithmetic), such that performance peaks at a certain level of arousal—a peak that occurs more or less regularly at a specific point in the day (Yoon, May, & Hasher, nd). Clear age differences appear to exist in circadian arousal patterns too, with older adults tending strongly toward morningness (vs. eveningness) than their younger counterparts—seemingly reaching their mental peak early in the day.Pain’s another important—but often ignored— variable to consider, particularly because it represents one of the most widely cited symptoms underlying disability among older adults (Patel et al., 2013). Pain draws attention—  draining valuable, scarce cognitive resources away from the individual (Seminowicz & Davis, 2006). In fact, several converging lines of evidence suggest that pain processing can interfere with cognitive processes and visa versa, with many studies demonstrating deficits in cognitive ability among older chronic pain suffers (Seminowicz & Davis, 2006). Medication side effects may exacerbate contributions of pain to performance, too.“I remember when I was a student running older participants,” recalls Black, “I would have to adjust their seats in the lab so that they could be comfortable, not having to constantly tilt their heads to see the screens or sit for so long that their pain would start to distract them from the task.”“I remind my students to make similar adjustments,” she adds.So what?Overarching the enterprise of science— psychological or otherwise— is the goal of reducing measurement error. Why? Simply put, error of any kind (random or systemic) reduces validity—our ability to measure what we claim, or purport, to be measuring. Even more importantly, it compromises our ability to detect true effects. Methodological flaws perpetuate Type I and Type II errors— false positives and false negatives respectively—that can transmit (dangerous) falsehoods throughout science and beyond.Of course, we can’t ignore error—we’ve got to do the exact opposite: recognize that sucker and manage it.Some errors, like those endogenous to individuals, are largely unpreventable. No matter what we do as researchers, we’ll probably never eliminate participants’ anxieties, reverse their hearing loss, or quell the knee pain that they inevitably bring to the testing situation. But we can make adjustments to accommodate those limitations.  And of course, failure to consider sources of random error may eventually translate to systemic error, contaminating the study itself.“I cannot emphasize enough the importance of making adjustments for your participants,” reminds Black.“For example, if the goal of the study is to assess central rather than perceptual processing, you need to ensure that older adults will be able to process stimuli as well as a younger adult- otherwise you’re not really measuring what you’re trying to measure” she adds.Error management strategiesAdmittedly, attempting to manage these complexities may feel dizzying.  So, where do you start and how can you do it?General strategies“First things first,” warns Black, “older adults are quite perceptive and don’t respond well to being patronized or infantilized. Always be patient, empathetic, and respectful.”And before getting down to the whole business of testing, don’t hesitate to initiate conversation—it builds rapport and reinforces motivation.“Older adults also tend to be more personal than college-aged students,” observes Kraemer. “They seem much more interested in the research than college aged students.”Amer agrees: “Motivation can sometimes be an issue with younger adults who are participating for course credit—such typically isn’t the case for older adults,” he explains. “And because older adults generally tend to be more interested in learning about my research, I always make sure that I spend as much time as I can discussing any issues that interest them as well as answering any questions that they may have.”The American Psychological Association’s (APA) working group on the older adult makes a similar suggestion, urging researchers to familiarize older adults with the purpose and procedures of testing.  Older adults, especially those with little formal education, may be more cautious in responding otherwise.“Older adults with a low level of education may also struggle with tasks that involve certain words as stimuli, instructions or informed consents written in language that is not easily understandable,” adds Kraemer. “For your sake and theirs, keep everything simple.”Also do what you can to ensure optimal performance, like reminding older adults prior to their testing appointment to bring all necessary assistive devices with them, including hearing aids or eyeglasses. I’ve even known a few researchers who kept bifocals on site.Strategies for managing sensory impairmentsComputer-based protocols, like many in experimental psychology, can exacerbate visual symptoms commonly causing discomfort among older users (Ko et al., 2014).“Some, but not all, adults also have limited experience with computers,” warns Kraemer. “A few express displeasure or apprehension toward even completing a study once they find out it involves a computer, others simply just require time to adjust to it,” he explains.One option, of course, includes administering paper assessments—but that obviously isn’t always feasible and can quickly get messy. Another management option includes altering features of the interface itself.Sound ophthalmological evidence suggests that because of their lower visual performance, older adults may be more susceptible to reduced visibility from glare than younger adults (Ko et al., 2014). Additional research indicates that they make take longer to perform visual tasks requiring repetitive transitions between brighter and dimmer areas than their younger counterparts (Ko et al., 2014).Creating a well-lighted environment, aimed at reducing glare and uneven luminance includes one simple approach to accommodating the visual limitations common among older adult participants.“Enlarging the font on documents and digital interfaces can also help ease eye strain due to presbyopia in this population,” adds Dr. Jack Parker, ophthalmologist at the Callahan Eye Hospital in Birmingham, Alabama.“On the other hand,” shares Kraemer, “I know researchers who have personally used the mouse or keyboard for their participants, simply using verbal communication to respond to tasks” if and when these adjustments cannot be made or if participant discomfort persists.“I just try to keep everything simple—using only two buttons for instance, and labeling them with brightly colored stickers so that they’re user friendly,” he adds.Regarding managing hearing deficits, the National Institute on Aging (NIA) recommends talking slowly, clearly, and in a normal tone—particularly because speaking in a raised or high-pitched voice actually distorts language sounds and can give the impression of anger.  Other suggestions include facing the person directly, at eye level, so that (s)he can lip-read or pick up visual clues.Strategies for managing cognitive impairments“If I sense that a participant appears to approach cognitive tasks with some apprehension or anxiety,” shares Black, “I often reassure them that they will perform fine. I also emphasize how much their participation contributes to science and our knowledge about cognitive aging generally.”“Reassuring them that their results will remain confidential also eases some anxiety,” she adds.Accordingly, many experts recommend using encouragement and verbal reinforcement liberally throughout testing with older adults, not only to quell uneasiness, but also to sustain motivation and rapport.  And because older adults tend to tire more easily than youngsters, designing rest breaks into your protocol appears to help manage some the ‘brain drain’-associated fatigue participants may experience over the course of testing. You might also consider using multiple testing sessions to reduce participant burden.Another strategy for optimizing performance includes scheduling testing appointments earlier (versus later) in the day, when cognitive arousal tends to be highest for older adults. Of course, asking what your participants would prefer never hurts either.Finally, deemphasizing the assessment of memory during the instruction phase of the study may be another way of reducing anxiety. In a study of younger and older adults, researchers varied the instructions they gave to participants before completing a memory task, either emphasizing that memory was going to be assessed or deemphasizing the memory component of the task (Rahhal et al., 2001). Specifically, when older adults were told that the experiment was testing their ability to learn facts instead of remember them, they performed as well as young adults; the exact inverse, however, emerged when older participants were asked to remember (Chasteen, 2005). Thus, subtle but sensitive alternations in language may reduce the anticipatory anxieties that tend to subvert older adults’ cognitive performance.  Of course, this strategy may require participant debriefing.Strategies for managing physical and physiological impairments“Finally, some older adults have limited mobility,” reminds Kraemer. “More than likely, you will encounter people with wheelchairs, assistive devices, or tremors.”For this reason, whenever possible, the assessment space should be arranged to accommodate wheelchairs or other assistive devices for those with physical limitations.  Accessibility of the space itself should also be considered:  Are there ramps? Elevators? Is parking convenient, close, well-lit, and safe?“Limited mobility can also mean that the older adults do not drive, in some cases,” Kraemer adds. “In order to get a large enough sample in a typical college town, it may be best to design an experiment that can travel and be conducted in a home, church, or another community that older adults have regular access to, rather than asking them to all come to an existing lab space.”Assessing and reducing pain when possible, as well as considering the effects of medication on performance, include other effective management techniques.ConclusionWorking with older adults is in equal measure rewarding and complex.
