Manual tapping enhances visual short‐term memory performance where visual and motor coordinates correspond

Visuo‐manual interaction in visual short‐term memory (VSTM) has been investigated little, despite its importance in everyday tasks requiring the coordination of visual perception and manual action. This study examines the influence of a manual action performed during stimulus learning on a subsequent VSTM test for object appearance. The memory display comprised a sequence of briefly presented 1/f noise discs (i.e., possessing spectral properties akin to natural images), wherein each new stimulus was presented at a unique screen location. Participants either did (or did not) perform a concurrent manual action (spatial tapping) task requiring that a hand‐held stylus be moved to a position on a touch tablet that corresponded (or did not correspond) to the screen position of each new stimulus as it appeared. At test, a single stimulus was presented, either at one of the original screen positions, or at a new position. Two factors were examined: the execution (or otherwise) of spatial tapping at a corresponding or non‐corresponding position, and the presentation of test stimuli either at their original spatial positions, or at new positions. We find that spatial tapping at corresponding positions elevates VSTM performance by more than 15%, but this occurs only when stimulus positions are matched from memory to test display. Our findings suggest that multimodal attentional focus during stimulus encoding (incorporating visual, spatial, and manual components) leads to stronger, more robust memory representations. We posit several possible explanations for this effect.     

Perceived Benefits Following Sport Injury: A Qualitative Examination of their Antecedents and Underlying Mechanisms

The purpose of the present study was to describe the development and validation of the Self-Talk Questionnaire (S-TQ), designed to measure two functions of self-talk strategies, namely the motivational function and the cognitive function, used by athletes to enhance their sport performances. The study was conducted in three phases. The first phase targeted item selection and content relevance. The second phase set out to test the factor structure of the instrument. The aim of the third phase was focused on further examination of the psychometric properties of the instrument. The results of an exploratory factor analysis provided adequate support for the instrument. The S-TQ consists of 11 items, representing two factors (motivational and cognitive). A confirmatory factor analysis showed an acceptable fit to the data. The factors were internally consistent, the correlations with external criteria were significant, and test-retest reliability values were very good. Examining the relationships between the S-TQ and similar constructs supported convergent validity. Discriminant validity was supported by correlations between the S-TQ and a different construct. The S-TQ appears to be a promising psychometric instrument that can be used in research and psychological intervention programs.     

An Investigation into the Effects of Hypnosis on Basketball Performance

Abstract

The purpose of this study was to investigate the effects of hypnosis on set- and jump-shooting performance among male collegiate basketball players. A single-subject ABA research design combined with a procedure that monitors the internal experience of the participants (Wollman, 1986) was implemented. The results indicated that all three participants increased their mean jump- and set- shooting performance from baseline to intervention, with all three participants returning to baseline levels of performance postintervention phase. Finally, each participant reported they had felt the intervention had increased sensations they associated with peak performance. These results support the hypothesis that a hypnosis intervention can improve jump- and set-shooting performance and increase feelings and cognitions that are associated with peak performance.     

ELIA: A software application for integrating spoken language and eye movements

We have developed a new software application, Eye-gaze Language Integration Analysis (ELIA), which allows for the rapid integration of gaze data with spoken language input (either live or prerecorded). Specifically, ELIA integrates E-Prime output and/or .csv files that include eye-gaze and real-time language information. The process of combining eye movements with real-time speech often involves multiple error-prone steps (e.g., cleaning, transposing, graphing) before a simple time course analysis plot can be viewed or before data can be imported into a statistical package. Some of the advantages of this freely available software include (1) reducing the amount of time spent preparing raw eye-tracking data for analysis; (2) allowing for the quick analysis of pilot data in order to identify issues with experimental design; (3) facilitating the separation of trial types, which allows for the examination of supplementary effects (e.g., order or gender effects); and (4) producing standard output files (i.e., .csv files) that can be read by numerous spreadsheet packages and transferred to any statistical software.     

Deservingness,liking relations,schadenfreude, and other discrete emotions in the context of the outcomes of plagiarism

This study investigated effects of like/dislike relations on schadenfreude and other discrete emotions in the context of plagiarism. The predicted emotions were derived from a structural analysis of how the appraisal of deservingness affects emotional reactions to positive or negative outcomes for self or other. One hundred forty‐six undergraduate participants responded to scenarios in which either hypothetical self or other (a classmate) plagiarised information from the internet for a class assignment and either received a high grade (undeserved outcome) or a penalty (deserved outcome). Hypothetical self was represented as either high or low in self‐esteem, other as liked or disliked. As predicted, liking relations moderated perceived deservingness. Schadenfreude (or pleasure) occurred when the disliked classmate received a deserved penalty for detected plagiarism but not when he/she suffered an undeserved positive outcome. This difference was reversed for the emotion of disappointment. Effects on other discrete emotions such as guilt and resentment are also reported.     

Caregivers’ beliefs about dementia: findings from the IDEAL study

Abstract

Objective: Informal caregivers of people with dementia develop their own beliefs about the condition, referred to as Dementia Representations (DRs), as they try to make sense of the changes they are observing. The first aim of this study was to provide a profile of the types of DRs held by caregivers. The second aim was to examine the impact of caregivers’ DRs on their well-being, satisfaction with life (SwL) and caregiving stress.

Methods: Participants were 1264 informal caregivers of people in the mild-to-moderate stages of dementia from time-point 1 of the IDEAL cohort study.

Measures: DRs were measured using questionnaire items covering: Identity, Cause, Control, and Timeline.

Results: Almost half (49.2%) of caregivers used a diagnostic term to describe the person’s condition, although 93.4% of caregivers stated they were aware of the diagnosis. Higher well-being, SwL, and lower caregiving stress were associated with the use of an identity term relating to specific symptoms of dementia, attributing the cause to ageing or not knowing the cause, and believing the condition would stay the same. Lower well-being, SwL, and higher caregiving stress were associated with believing there was little that could be done to control the effects of the condition.

Conclusion: Healthcare professionals should assess and gain an understanding of caregivers’ DRs in order to provide more tailored information and support.
