Human gaze behaviour during action execution and observation

Gaze shifts and fixations appear to be proactive in both action execution and observation. We investigated a dependency of anticipatory gaze behaviour by using a block stacking task. Blocks were rectangles depicted on a computer screen and the stacking movements were controlled via computer mouse. Subjects either had to execute the task or had to observe it made by the experimenter, or by the computer. The dependency of gaze behaviour on the visibility of a virtual effector, the visibility of the actor, and the nature of the actor was tested by measuring eye movements. Anticipatory eye movements were predominant when the subjects themselves executed the task. During action observation, gaze behaviour did neither depend on the visibility nor depend on the nature of the actor. However, big variability was found between the subjects suggesting the use of two different strategies in action observation: some subjects were mainly tracking the blocks during stacking movements; others were strongly anticipating. We suggest that gaze behaviour during action observation is not predetermined by rigid neural circuitry, but strongly depends on the context. The possibility to explain the causal mechanism, as well as the ownership of the action may be crucial preconditions for anticipatory gaze behaviour.     

Mood induced cognitive and emotional reactivity, life stress, and the prediction of depressive relapse

This study examined a group of participants who were fully remitted from a previous episode of major depressive disorder, and evaluated the role of cognitive and emotional reactivity to a mood challenge, and life stress in the prediction of relapse. Fifty-two participants were evaluated during remission, and their reactivity (i.e., change in dysfunctional attitudes and emotional state) to a depressed mood induction was evaluated. The cohort was followed up 12 months after the initial assessment. Thirty-five percent of the sample experienced a relapse during the follow-up period. Relapse was predicted by higher rates of life stress, and lower levels of emotional reactivity (specifically less reduction in happiness) to the mood induction during the initial assessment. Cognitive reactivity to the mood induction did not predict relapse, nor did the interaction between cognitive reactivity and life stress. These findings are discussed in terms of recent literature suggesting that depression is associated with insensitivity to emotion context, such that depressed individuals display blunted emotional responses to affective stimuli, including sadness-inducing stimuli. These findings suggest that insensitivity to emotional context may also be a characteristic of euthymic individuals at risk of relapse.     

Ruminative self-focus, negative life events, and negative affect

Ruminative thinking is believed to exacerbate the psychological distress that follows stressful life events. An experience-sampling study was conducted in which participants recorded negative life events, ruminative self-focus, and negative affect eight times daily over one week. Occasions when participants reported a negative event were marked by higher levels of negative affect. Additionally, negative events were prospectively associated with higher levels of negative affect at the next sampling occasion, and this relationship was partially mediated by momentary ruminative self-focus. Depressive symptoms were associated with more frequent negative events, but not with increased reactivity to negative events. Trait rumination was associated with reports of more severe negative events and increased reactivity to negative events. These results suggest that the extent to which a person engages in ruminative self-focus after everyday stressors is an important determinant of the degree of distress experienced after such events. Further, dispositional measures of rumination predict mood reactivity to everyday stressors in a non-clinical sample.     

To Practice What We Preach: The Use of Hypocrisy and Cognitive Dissonance to Motivate Behavior Change

When people fail to practice what they preach, their act of hypocrisy can induce cognitive dissonance and the motivation to change their behavior. The current paper examines the evidence for this assumption by reviewing and analyzing the research that has used the hypocrisy procedure to influence the performance of pro‐social behaviors related to health, the environment, and interpersonal relations. The first section looks at the evidence for the claim that hypocrisy motivates behavior change as opposed to other forms of dissonance reduction such as attitude change. We then review studies that suggest that the induction of hypocrisy exerts its greatest effect on behavior change when people publicly advocate the importance of the target course of action and are then privately reminded of their own recent personal failures to perform the target behavior. A third section discusses the limitations to the current body of work and important directions for future research. Finally, the paper concludes with a discussion of how the hypocrisy procedure relates to other contemporary models of behavior change.     

Lying in the name of the collective good: a developmental study

The present study examined the developmental origin of 'blue lies', a pervasive form of lying in the adult world that is told purportedly to benefit a collective. Seven, 9-, and 11-year-old Chinese children were surreptitiously placed in a real-life situation where they decided whether to lie to conceal their group's cheating behavior. Children were also assessed in terms of their willingness in hypothetical situations to endorse lying or truth-telling that benefits a collective but at the same time harms an individual. Results showed that as age increased, children became more inclined to endorse lying in the name of the collective good, and to tell lies for their group themselves. Furthermore, children's endorsement about blue lies in hypothetical situations predicted their actual lying behavior.     

Infants lost in (peripersonal) space?

A significant challenge in developing spatial representations for the control of action is one of multisensory integration. Specifically, we require an ability to efficiently integrate sensory information arriving from multiple modalities pertaining to the relationships between the acting limbs and the nearby external world (i.e. peripersonal space), across changes in body posture and limb position. Evidence concerning the early development of such spatial representations points towards the independent emergence of two distinct mechanisms of multisensory integration. The earlier-developing mechanism achieves spatial correspondence by representing body parts in their typical or default locations, and the later-developing mechanism does so by dynamically remapping the representation of the position of the limbs with respect to external space in response to changes in postural information arriving from proprioception and vision.     

Time of day affects episodic memory in older adults

The neuropsychological test scores of 2030 cognitively normal older adults were examined to evaluate performance patterns as they related to time of day (TOD) at which testing was initiated. Multiple regression analyses were used to examine the association of TOD with scores on seven neuropsychological tests used in the clinical evaluation of dementia. Episodic memory performance was significantly related to TOD, while memory span and verbal fluency were not. Best performance occurred during early morning hours and late afternoon; worst performance occurred mid-day (i.e., noon). These findings may have implications for clinical assessment, the design of research on dementia, and the daily functioning of older adults.     

Parental involvement in competitive youth sport settings

ObjectivesBased on ecological systems theory [Bronfenbrenner, U. (2005). Making human beings human: Bioecological perspectives on human development. Thousand Oaks, CA: Sage], the purpose of this study was to examine parents’ involvement in competitive youth sport settings.DesignData were collected through two distinct phases of fieldwork. Phase 1 involved longitudinal data collection with four families. Phase 2 involved observations of youth soccer settings.MethodData were collected from four families via individual interviews and audio-diaries and were supplemented through 120 h of observation. Data were transcribed verbatim and analyzed using grounded theory methodology.ResultsParents’ verbal reactions to their children's sport performance behaviors were placed on a continuum moving from more supportive to more controlling comments. These comments were categorized as praise/encouragement, performance contingent feedback, instruction, striking a balance, negative comments, and derogatory comments. Parents experienced empathy in that they perceived sharing the emotions their children felt in sport, and these emotions appeared to change in relation to dynamic game and contextual circumstances. Parents also thought that they possessed knowledge and expertise of sport, which they perceived enabled them to make comments to their children.ConclusionA series of reciprocal and bi-directional relationships were central to parents’ involvement in competitive youth sport.     

Perceived Control as a Moderator of the Prototype Effect in the Perception of Discrimination

Whether an individual's behavior is perceived as discriminatory has a great deal to do with the characteristics of the individual. The prototype effect refers to the finding that individuals who match people's prototypes of the typical executor of a particular kind of discrimination (e.g., the prototypical sex discriminator is male) are much more likely to receive attributions of discrimination than are nonprototypical executors. The motivated social cognition perspective, however, suggests that people's subjective needs will influence the extent to which they rely on simplified cognitive abstractions. The results of this study indicate that people's subjective perceptions of control over discrimination in their lives moderate the influence of the prototype effect on perceptions of discrimination in ambiguous situations.
