Grip strength and fatigue in junior college tennis players.

Change in grip strength over 30 trials was documented in two samples of junior college tennis players to assess possible fatigue. Eight men and eight women performed 30 maximum-grip strength tests with 25-sec. rests between trials. Significant positive correlations (.38 and .53 for men and women) were observed between grip strength and trials. In practical terms, grip strength did not change over 30 trials in these tennis players. The data suggested that the repetitive gripping patterns used by these players in tennis play resulted in consistent maximum-grip strengths across 30 trials.     

Differential cognitive substrates of verbal episodic memory performance in semantic variant primary progressive aphasia and Alzheimer’s disease

Performance on neuropsychological measures of verbal memory requires cognitive abilities beyond memory. We examined the contribution of semantic knowledge in verbal episodic memory for semantic variant primary progressive aphasia (svPPA) or Alzheimer’s disease (AD). 415 AD and 68 svPPA participants completed measures of episodic memory (visual and verbal) and semantic knowledge. A double dissociation existed visual recall predicted verbal recognition in AD, whereas semantic knowledge contributed to verbal recognition in svPPA.     

Individual differences in face and voice matching abilities: The relationship between accuracy and consistency

Deciding whether two different face photographs or voice samples are from the same person represent fundamental challenges within applied settings. To date, most research has focussed on average performance in these tests, failing to consider individual differences and within‐person consistency in responses. Here, participants completed the same face (Experiment 1) or voice matching test (Experiment 2) on two separate occasions, allowing comparison of overall accuracy across the two timepoints as well as consistency in trial‐level responses. In both experiments, participants were highly consistent in their performances. In addition, we demonstrated a large association between consistency and accuracy, with the most accurate participants also tending to be the most consistent. This is an important result for applied settings in which organisational groups of super‐matchers are deployed in real‐world contexts. Being able to reliably identify these high performers based upon only a single test informs regarding recruitment for law enforcement agencies worldwide.     

Introduction to the Special Section ‘Innovative counselling and psychotherapy research methods’: Defining the future of counselling and psychotherapy research

In the call for papers for this Special Issue, we sought submissions that would introduce innovative methods with the potential to shape counselling and psychotherapy research into the future. We believe that we accomplished this goal and that this issue introduces a range of valuable examples of current innovations in counselling and psychotherapy research methods. Through the review process, we encouraged authors to offer practical guidelines on how to innovatively assess and analyse change and other relevant aspects of therapy. We also guided authors to not only provide the field with an update on cutting‐edge methodology, but also describe these methods in a practice‐friendly way. As such, the Special Issue aims at becoming a building block for future practice‐friendly research in counselling and psychotherapy.     

The interactive effects of duality expertise and coping frames on responses to ambivalent messages

We examine the interactive effects of biculturals' duality expertise and externally provided coping resources on attitudinal responses to ambivalence. Three studies reveal that ambivalence is associated with greater discomfort for biculturals more (vs. less) conflicted about their cultural duality and with limited exposure to accessing their two cultural knowledge systems simultaneously. Among biculturals with lower duality expertise, coping frames lower their negative evaluation of messages that elicit ambivalence because coping frames help these biculturals resolve the discomfort associated with ambivalence. Provision of coping frames does not impact attitudes of biculturals with greater levels of duality expertise.     

The size of an attentional window modulates attentional capture by color singletons

Researchers have proposed that during visual search, a color singleton cannot capture attention in a bottom-up fashion (Jonides & Yantis, 1988). In the present study, we manipulated the size of the attentional window by asking participants to detect either a global (diffuse attention) or a local (focused attention) shape before starting the search for a nonsingleton target. We demonstrate that increasing the size of attentional window causes the observers to frequently orient to an irrelevant color singleton. We conclude that although the size of attentional window might be under a top-down control, within the attentional window, an irrelevant salient singleton can capture attention in a bottom-up fashion.     

A Psychobiographical Analysis of Faith, Hope, and Despair in Suicide

This paper presents a psychobiographical analysis of a young woman who committed suicide over 50 years ago. Among the documents analyzed are her letters, a high-school diary, creative writing, college newspaper book reviews, and academic papers. Using both an Eriksonian and object-relational theoretical framework, the roles of faith, hope, and despair in suicide—and the ways in which these were represented in the young woman's self-system—are analyzed. Although she possessed strong elements of both faith and hope, along with a will to implement them in a purposeful manner, she was prone to the defense mechanisms of splitting, devaluation, and dissociation, which led to an inability to create an abiding sense of self that may have prevented her descent to despair. Among other issues discussed in the article are the usefulness of psychobiography as a method of studying suicide and both the benefits and limitations of spiritual faith in countering depression and suicide.     

The role of the native language in auditory and visual context effect modalities

Facilitation of memory for target stimuli due to similar context in the learning and testing phases is known as “context effect” (CE). The present study aimed to investigate the interaction between CE as elicited by the consistency of the language of presentation (Hebrew vs. English) with the native language (Hebrew vs. English) in both auditory and visual modalities. Overall, 120 individuals participated in the experiment. As predicted, CE was evident when the language of presentation remained consistent between study and test. Contrary to our prediction, Hebrew speakers remembered more English words, and vice versa. A possible explanation is that this difference is due to the cognitive effort invested when processing a less dominant language, thus resulting in better recognition. This study has several practical implications, including a recommendation that academic institutions test students in the language in which the material was presented in order to measure the students' knowledge more accurately.
