Effects of test anxiety on motor learning: The processing efficiency hypothesis

Abstract

The hypothesis that, under test (stress) conditions, high trait-anxious individuals invest extra processing resources to reach motor learning levels similar to those of low-anxious individuals was investigated. A transfer procedure (practice trial, rest interval, and transfer trial) was employed to analyse motor learning effects. In Experiment 1, a secondary task (click detection) was used to measure the extra processing resources expenditure on motor learning during the practice trial. Neither motor performance in the transfer trial nor secondary task performance differed as a function of test condition or anxiety trait. A critical analysis of the secondary task paradigm suggested that it was not sensitive enough to reflect the amount of processing capacity expended on the primary motor tasks. In Experiment 2, subjects performed a loading task (verbal shadowing of sentences) concurrently with the motor tasks during the practice trial to prevent extra resources from being allocated to motor learning. Results showed that anxiety trait was associated to performance time increments on the high-demanding motor tasks in the transfer trial. A plausible explanation is that anxiety impairs learning because it reduces the efficiency of processing. An alternative interpretation, concerning an ability deficit of high trait-anxious individuals, is discussed.     

Piecing Together Ideas on Sociocultural Psychology and Methodological Approaches

In this commentary, I will piece together some transversal ideas throughout the articles that compose the thematic issue Self-identity on the move: methodological elaborations focusing on two main aspects: (i) the relation between the individual and the society and how self-identity is constructed in context; and (ii) data generalization in qualitative studies. I will base my commentary on the reflections brought forth by the articles on these two topics. My aim is to trace a line on which the authors, in their contributions to this issue, dialogue among each other with respect to the key elements of the individual, the social context, the (self)identity, and data generalization in qualitative research.     

Glass maze in women's leadership

Psychological gender discrimination explanations have changed over the past thirty years, becoming more complex in order to obtain a better understanding of the social reality. At the present moment, one of the most interesting research areas is the one referring to the 'glass maze' phenomenon in women's management careers. The main purpose of this work is to reveal the theoretical evolution in an attempt to explain the leadership study from a gender perspective. The consecutive hypotheses, starting with the labour sexual division idea, are becoming more interactive in order to understand the current labour-social situation. Social psychology has underlined the role of beliefs, observed via gender stereotyped roles, prejudiced attitudes against women, sexist and neo-sexist ideology, or masculine, feminine and androgynous identity development. New psychological interpretations insist on the variability of the gender concept, where gender is sometimes observed through men and women's behaviours, and other times through those behaviour expectations. But gender is mainly observed though the power relations between men and women during social interactions in labour organizations.     

Science–Practice Gap in e‐Recruitment

We conducted a content analysis of online job application forms used by companies listed on the Spanish Stock Exchange (i.e., Bolsa de Madrid). We collected data from 76 companies in 2005 and then again for 66 of these companies in 2009. We coded the type of information required on the application forms based on 24 categories related to potential illegal discrimination and personnel selection social context issues (i.e., fairness, intrusiveness, and privacy). Results indicated that the relative frequency of the 24 information categories has remained stable from 2005 to 2009. Moreover, averaging 2005 and 2009 results, a large percentage of companies require information that can be used for illegal discrimination and can be perceived as unfair, intrusive, and invasive of applicants' privacy such as age or date of birth (87%), nationality (61%), marital status (48%), place of birth (57%), passport number (47%), a photograph (23%), and number of children (11%). Our results document a science–practice gap in e‐recruitment because scholarly research suggests that requesting these types of information leads to negative applicant reactions ranging from negative perceptions and emotions to actually initiating legal action against the recruiting firm. Our results also point to e‐recruitment as an area that could be targeted as a good collaboration topic between scientists and practitioners because the resulting research has the potential to make important contributions toward bridging the science–practice gap.     

Predictors of HIV-related stigma among young people living with HIV.

Enacted and perceived HIV stigma was examined among substance-using young people living with HIV (YPLH) in Los Angeles, San Francisco, and New York City (N = 147). Almost all YPLH (89%) reported perceived stigma, and 31% reported enacted experiences in the past 3 months; 64% reported experiences during their lifetime. The HIV stigma questions were characterized by factors of avoidance, social rejection, abuse, and shame. In multivariate models, enacted stigma was associated with gay or bisexual identity, symptomatic HIV or AIDS, and bartering sex. Perceived stigma was associated with female gender, symptomatic HIV or AIDS, bartering sex, lower injection drug use, and fewer friends and family knowing serostatus. Gay or bisexual YPLH who were also HIV symptomatic or AIDS diagnosed experienced more HIV stigma than their heterosexual peers.     

What can we learn from psychoanalysis and prospective studies about chemically dependent patients?

Despite the common occurrence of drug abusers in the psychoanalytic clinic, contemporary literature on the subject, particularly among publications in the IJP, is sparse. This paper aims to review the most important psychoanalytic contributions on drug dependency in the past 100 years, then attempts to compare their postulations to the findings ofpertinent prospective studies. In these patients, a persistent symbiotic object relationship is found, which ties them to narcissistic functioning, where drug use is viewed in the light of both pleasure without object and omnipotently controlled need. The author also discusses the possible contribution of the mother and father in the genesis of this condition, focusing on the compromise of the paternal function as the deciding factor. The theoretical and technical implications of this approach are illustrated by clinical material.     

Youth Exposed to Violence: Stability, Co-occurrence, and Context

With considerable literature establishing how separate types of violence disrupt the lives of children, there is emerging interest in examining violence across multiple interpersonal domains. This article examines four commonly occurring and frequently researched domains of violence exposure: marital physical aggression, mother-to-youth aggression, father-to-youth aggression, and community violence. A community-based sample of 103 parents and youth provided three waves of data at annual intervals beginning when the youth were aged 9–10. We explored stability of exposure, co-occurrence across different types of violence exposure, and associations with co-occurring risk factors. Approximately 30–45% of youth reported intermittent exposure over the 3 years. In addition to overlap among types of violence exposure within the family, we found overlap between parent-to-youth aggression and community violence, an association that was exacerbated in families where fathers reported high levels of global distress symptoms. Mother-to-youth, father-to-youth, and community violence related to youth behavior problems beyond the contextual risk factors of low income, stressful life events, and parents’ global distress symptoms. These results highlight the importance of examining violence longitudinally, across multiple types, and with attention to contextual factors.     

Alpha2A-adrenoceptor stimulation improves prefrontal cortical regulation of behavior through inhibition of cAMP signaling in aging animals

The working-memory functions of the prefrontal cortex (PFC) are improved by stimulation of postsynaptic, alpha2A-adrenoceptors, especially in aged animals with PFC cognitive deficits. Thus, the alpha2A-adrenoceptor agonist, guanfacine, greatly improves working-memory performance in monkeys and rats following systemic administration or intra-PFC infusion. Alpha2A-adrenoceptors are generally coupled to Gi, which can inhibit adenylyl cyclases and reduce the production of cAMP. However, no study has directly examined whether the working-memory enhancement observed with guanfacine or other alpha2A-adrenoceptor agonists results from cAMP inhibition. The current study confirmed this hypothesis in both rats and monkeys, showing that treatments that increase cAMP-mediated signaling block guanfacine's beneficial effects. In aged rats, guanfacine was infused directly into the prelimbic PFC and was challenged with co-infusions of the cAMP analog, Sp-cAMPS. In aging monkeys, systemically administered guanfacine was challenged with the phosphodiesterase 4 inhibitor, rolipram, using intramuscular doses known to have no effect on their own. In both studies, agents that mimicked the actions of cAMP (rats) or increased endogenous cAMP (monkeys) completely blocked the enhancing effects of guanfacine on working-memory performance. These results are consistent with alpha2A-adrenoceptor stimulation enhancing PFC working-memory function via inhibition of cAMP-mediated signaling.     

UK and Spanish stranger sexual offenders crime scene behaviours and previous convictions: A cross-cultural comparison

International comparisons of previous convictions (PC) and crime scene behaviours (CSB) of stranger sexual offences can inform offender profiling strategies; especially the degree to which pragmatic models cross validate across countries. The present study compared PC and CSB of 474 UK and 418 Spanish cases. CSB and PC were analysed using Chi-square. UK stranger sexual offenders displayed a higher proportion of all CSB analysed. UK offenders also had a significantly higher proportion of PC with the exception of violence offences. There were no significant differences in sexual pre-convictions. In both the UK and Spain the CSB ‘reference to the police’ was significantly association with the PC ‘Criminal damage’ no other similar significant associations were found. Explanations for these findings include differences between the countries in regards to: legislation, crime recording processes, data coding processes, with additional consideration of any cultural, environmental and contextual factors.     

On the relation between spontaneous trait inferences and intentional inferences: An inference monitoring hypothesis

More than twenty five years after the beginning of research on spontaneous trait inferences (Winter & Uleman, 1984) an intriguing paradox in the impression formation literature remains: if traits are spontaneously inferred, why aren't they used to organize behavioral information and thereby facilitate recall under memory instructions (Hamilton, Katz, & Leirer, 1980)? We hypothesized that organization by traits is more evident under impression formation goals because only in that case then are inferences sufficiently monitored to permit their use in organizing impressions. As a consequence, such monitored traits can then be used strategically as retrieval cues. Merging the main features of the Winter and Uleman and the Hamilton et al. experimental paradigms, Experiment 1 simultaneously replicated the main results of both studies. Using a new recognition paradigm, Experiments 2 and 3 further tested this inference monitoring hypothesis by showing that monitoring of trait inferences only occurs under particular processing goals, and is dependent on the availability of cognitive resources.
