Apparatus accurate delays for auditory feedback experiments

This note describes a way of modifying a tape recorder for producing accurately controllable delays for experiments with delayed auditory feedback. Any value of delay from 80 millisec. to 1.2 sec. can be obtained to the nearest millisec., and the range could be extended by some minor changes. The delay is continuously monitored on a digital electronic timer.     

Motor affordance and its role for visual working memory: evidence from fMRI studies

We examined the role of motor affordances of objects for working memory retention processes. Three experiments are reported in which participants passively viewed pictures of real world objects or had to retain the objects in working memory for a comparison with an S2 stimulus. Brain activation was recorded by means of functional magnetic resonance imaging (fMRI). Retaining information about objects for which hand actions could easily be retrieved (manipulable objects) in working memory activated the hand region of the ventral premotor cortex (PMC) contralateral to the dominant hand. Conversely, nonmanipulable objects activated the left inferior frontal gyrus. This suggests that working memory for objects with motor affordance is based on motor programs associated with their use. An additional study revealed that motor program activation can be modulated by task demands: Holding manipulable objects in working memory for an upcoming motor comparison task was associated with left ventral PMC activation. However, retaining the same objects for a subsequent size comparison task led to activation in posterior brain regions. This suggests that the activation of hand motor programs are under top down control. By this they can flexibly be adapted to various task demands. It is argued that hand motor programs may serve a similar working memory function as speech motor programs for verbalizable working memory contents, and that the premotor system mediates the temporal integration of motor representations with other task-relevant representations in support of goal oriented behavior.     

Changes in Neuroticism Following Trauma Exposure

Using longitudinal data, the present study examined change in midlife neuroticism following trauma exposure. Our primary analyses included 670 participants (M_age = 60.55; 65.22% male, 99.70% Caucasian) who completed the NEO Personality Inventory at ages 42 and 50 and reported their lifetime exposure to traumatic events approximately 10 years later. No differences in pre‐ and post‐trauma neuroticism scores were found among individuals who experienced all of their lifetime traumas in the interval between the personality assessments. Results were instead consistent with normative age‐related declines in neuroticism throughout adulthood. Furthermore, longitudinal changes in neuroticism scores did not differ between individuals with and without histories of midlife trauma exposure. Examination of change in neuroticism following life‐threatening traumas yielded a comparable pattern of results. Analysis of facet‐level scores largely replicated findings from the domain scores. Overall, our findings suggest that neuroticism does not reliably change following exposure to traumatic events in middle adulthood. Supplemental analyses indicated that individuals exposed to life‐threatening traumas in childhood or adolescence reported higher midlife neuroticism than individuals who experienced severe traumas in adulthood. Life‐threatening traumatic events encountered early in life may have a more pronounced impact on adulthood personality than recent traumatic events.     

Religious Confession and Symptom Severity: A Prospective Comparative Study

Little research has been done on comparing confessions regarding mental health. In the present study, 320 people (78 Buddhists, 77 Catholics, 89 Protestants and 79 Muslims) were compared in terms of their symptom severity. Buddhists and Protestants had lower scores than Catholics and Muslims for obsessive–compulsive behavior and hostility. Muslim group had the highest comparative scores for psychoticism. Buddhists and Protestants had comparatively low scores for paranoid ideation and overall symptom severity, with Catholics and Muslims having high ones. Results reveal that confession should be taken in account in psychological research and diagnosis, since it is explicitly associated with psychological well-being.     

Too Much of a Good Thing? Emotional Intelligence and Interpersonal Conflict Behaviors

Research suggests that the outcomes of interpersonal conflict are determined not only by the conflict itself, but also by the way in which it is handled. Confrontational and domineering tactics have been found to magnify the adverse impact of conflict. Thus, investigations of determinants of aggressive conflict management behaviors are of considerable interest. This study extends the literature by examining the relationship between conflict management preferences and conflict management behaviors and by examining how emotional intelligence (EI) shapes this preference-behavior relationship. Individuals’ conflict management preferences predicted actual conflict management behaviors. EI was found to moderate this relationship. However, some of these moderating effects run contrary to the popular view of EI as a prosocial concept. Specifically, some EI facets were found to strengthen the link between aggressive conflict management preferences and subsequent conflict management behaviors.     

False recollection of the role played by an actor in an event

Two experiments demonstrated that eyewitnesses more frequently associate an actor with the actions of another person when those two people had appeared together in the same event, rather than in different events. This greater likelihood of binding an actor with the actions of another person from the same event was associated with high-confidence recognition judgments and “remember” responses in a remember–know task, suggesting that viewing an actor together with the actions of another person led participants to falsely recollect having seen that actor perform those actions. An analysis of age differences provided evidence that familiarity also contributed to false recognition independently of a false-recollection mechanism. In particular, older adults were more likely than young adults to falsely recognize a novel conjunction of a familiar actor and action, regardless of whether that actor and action were from the same or from different events. Older adults’ elevated rate of false recognition was associated with intermediate confidence levels, suggesting that it stemmed from increased reliance on familiarity rather than from false recollection. The implications of these results are discussed for theories of conjunction errors in memory and of unconscious transference in eyewitness testimony.     

Racial/Ethnic Identity among Creole Peoples in Mauritius

This article provides the findings of qualitative research into the perceptions of racial/ethnic identity among the Creole community of Mauritius. Participants were 24 Creole Mauritians (males = 16, females = 8, age range = 22–69 years). Interview data were collected and analyzed primarily through a hermeneutic (phenomenoligically-oriented) (van Manen, 1997) process. Six major themes of racial/ethnic identity emerged: experiences of dis-ease, experiences of stuckness (ad-extra and ad-intra), epiphany experiences, experiences of self-appreciation, and experiences of hopeful optimism. The themes describe individual processes of racial/ethnic identity development as well as sociopolitical obstacles to positive identity formation among the Creole.     

Leaving Home: An Examination of Late‐Life Relocation Among Older Adults

This article describes older adults' experiences of a late‐life residential relocation from a home to a long‐term health care setting. Findings from 14 participants who engaged in a focus group and/or an individual interview supported 8 major themes. Thematic experiences were related to precipitating factors prior to the move, risks and protective factors in relocation, and aspects of positive aging. Implications for clinical practice with older adults who undergo late‐life transitions are described.     

Selecting from dynamic environments: attention distinguishes between blinking and moving

Pinto, Olivers, and Theeuwes (2006) showed that a static target can be efficiently found among different types of dynamically changing distractors. They hypothesized that attention employs a broad division between static and dynamic information, a hypothesis that conforms with earlier research. In the present study, we investigated whether attention can only make use of this crude division or can exploit more subtle discriminations within the dynamic domain. In Experiment 1, participants were able to efficiently find a blinking target among moving distractors and moving targets among blinking distractors, although all items changed at the same rate and produced the same change in local luminance. In Experiment 2, search for a dynamic target among dynamic distractors was aided when we gave the distractors additional dynamic cues. Experiment 3 showed that making the displays equiluminant affected search efficiency for a static target among moving distractors, but not among blinking distractors. The findings refute the broad division hypothesis and suggest that object continuity plays an important role in selection.
