Online corrections in children with and without DCD

Human arm movements need 'online' corrections due to noise in perception and action. A Step-Perturbation paradigm explored online corrections in control children and children with DCD aged between 7 and 13 years. Control children found the task straightforward: a distracter had no effect and they managed to stop relatively quickly. Children with DCD found the task difficult and the apparatus was modified accordingly (decreased postural and force production demands). The distracter affected some children with DCD and some found it difficult to stop. All of the DCD population showed poorer performance in both the perturbation and non-perturbation condition. Nevertheless, there was no interaction between group and condition. Thus, this study found no evidence for specific deficits in online correction mechanisms in DCD. We suggest that: (i) fundamental problems in generating basic movements can account for the documented difficulties in correcting on-going movements, and (ii) such fundamental difficulties make it very difficult to pinpoint specific mechanism deficits.     

Is aversion to incest psychologically privileged? When sex and sociosexuality do not predict sexual willingness

As human possess powerful incest-avoidance mechanisms (which likely evolved due to the high costs of inbreeding), reactions to incestuous sexual encounters may be psychologically distinct from reactions to non-incestuous (but still non-normative) sexual encounters. Accordingly, variables such as sex and sociosexuality that normally predict openness to sexual encounters in other situations (i.e., men and sociosexually unrestricted people tend to be more sexually willing) may not do so – or do so only weakly – in incestuous situations. In Study 1, sociosexuality predicted negative judgments of non-incestuous (but still normatively proscribed) sexual acts, but not judgments of incestuous sexual acts. In Study 2, sociosexuality predicted negative reactions to imagined sex with biologically unrelated (but still normatively unusual) partners, but not reactions to imagined sex with related partners (this effect was limited to women); also, men reacted less negatively than women to imagined sex with unrelated partners, but men and women reacted equally negatively to imagined sex with related partners (the latter effect was limited to sociosexually restricted men).     

Gender perspective in the context of Spanish academic psychology

The purpose of this study is to analyse the evolution of gender perspective in the context of the Spanish academic Psychology. The last three decades were analysed. In each decade, the study describes the groups and individuals who have contributed to the analysis of gender perspective in Psychology, the sponsoring institutions, and the most frequently used research strategies. Likewise, the study analyses the development of topics and areas in these three decades. The general trend shows that the interpretation of sex/gender has moved away from being considered an individual and internal factor to a more dynamic approach that analyses sex/gender through behavioural practices.     

Live interactive group-specific normative feedback reduces misperceptions and drinking in college students: a randomized cluster trial.

This research evaluated the efficacy of a live and interactive group-specific normative feedback intervention designed to correct misperceptions of alcohol-related group norms and subsequently reduce drinking behavior. Campus organizations (N = 20) containing 1,162 college students were randomly assigned to intervention or assessment-only control conditions. Participants in the intervention condition attended an intervention during their organization's regular standing meeting. Data were gathered in vivo using computerized handheld keypads into which participants entered personal responses to a series of alcohol-related questions assessing perceptions of normative group behavior as well as actual individual behavior. These data were then immediately presented in graphical form to illustrate discrepancies between perceived and actual behavioral group norms. Results indicated that compared with the control group, the intervention group reduced drinking behavior and misperceptions of group norms at 1-month and 2-month follow-ups. Changes in perceived norms mediated the reductions in drinking. Results demonstrate the effectiveness of a novel, technologically advanced, group-based, brief alcohol intervention that can be implemented with entire groups at relatively low cost.     

Coming to terms with coming out: review and recommendations for family systems-focused research.

For lesbian, gay, and bisexual (LGB) adolescents and young adults, coming out to family members, especially parents, is a major psychological decision and hurdle due to both perceived fears and actual negative consequences. But beyond the literature on factors associated with the decision to come out and parents' initial reactions to the disclosure, empirical studies of what unfolds afterward, and how the family adjusts to the LGB adolescent's identity over time, are sparse and scattered. This article reviews and integrates findings from studies of the individual-, dyadic-, and family-level variables associated with positive outcomes, focusing particularly on relationship variables. Methodological concerns within this body of research are discussed, and research recommendations are offered. A preliminary working model of how families successfully come to terms with coming out is proposed to guide future research that will advance theory and clinical work with LGB youth and their families.     

Fact learning: how information accuracy, delay, and repeated testing change retention and retrieval experience

Previous classroom studies have shown that the phenomenology of studied facts changes over time. However, pedagogical needs preclude both the study of errors and the separation of the effects that delay and repeated testing have on retention and retrieval experience. We addressed these issues together in an experiment where participants read stories containing correct and misleading information and provided Remember, Just Know, and Familiar judgements on immediate and delayed general knowledge tests. After 2 days, information learned from the stories shifted from Remembered to Just Known, but repeated testing attenuated this shift. Interestingly, similar patterns of retrieval and phenomenology were observed for correct and misleading information with one important difference--the shift over time to Just Knowing was significantly greater for correct than for misleading information. Together, these findings show the roles of information accuracy, delay, and testing in determining both retention and the subjective experience of retrieval.     

Getting technical about awareness

It has recently been argued that post-decision wagering provides an objective measure of awareness. We critically evaluate this claim, emphasizing the distinction between performance without awareness and a reluctance to gamble in full awareness of weak sensory evidence. We address two key methodological issues. The first is the design of the pay-off matrix to reward a strategy of wagering that reflects the strength of sensory evidence. The second is the use of signal detection theory to analyze the resulting data. We argue that proper treatment of these issues is essential if post-decision wagering is to prove valuable in validating claims of perception without awareness in normal subjects and neuropsychological patients.     

The paradox of Alypius and the pursuit of unwanted information

Prior work has found that people occasionally seek useless information, a violation of strict rationality. The present work examined whether and why curiosity can also cause individuals to seek predictably harmful information. In four studies, participants were given the opportunity to gain knowledge of questionable personal value. In each case, participants focused on their curiosity about the information and underweighted its consequences. As a result, participants tended to seek knowledge that they themselves believed they would be better off without. Consistent with Loewenstein’s [Loewenstein, G. (1996). Out of control: Visceral influences on behavior. Organizational Behavior and Human Decision Processes, 65, 272–292] analysis of visceral factors in decision making, these effects diminished with a time delay and when deciding whether to expose someone else to unpleasant information. These results shed light on a common yet paradoxical aspect of human behavior that presents a counterpoint to traditional hedonistic models of human motivation.
