Inhibitory processes in memory are impaired in schizophrenia: Evidence from retrieval induced forgetting

Schizophrenic patients are known to exhibit inhibitory impairments in response suppression and selective attention. However, the impairment of inhibitory control in memory retrieval has not clearly been documented. In two experiments, we investigate inhibition in memory retrieval by using the retrieval practice procedure. In Expt 1, a cued recall final test was used. Consistent with previous research, we found similar retrieval‐induced forgetting (RIF) effects in schizophrenic patients and in controls. However, these effects could be the result of interference/blocking or the results of inhibition. In order to reduce the influence of blocking in Expt 2, we used a recognition test. We found that RIF was reduced in patients, compared to healthy controls. The elimination of RIF effect in patients, when the influence of blocking is reduced, indicates that inhibitory processes in memory are altered in schizophrenia. Result suggest that schizophrenic patients suffer from critical impairments in inhibitory processes involved in memory retrieval, similar to the inhibitory deficits found in other cognitive domains.     

Cognition and native-language grammar: The organizational role of adjective-noun word order in information representation

In the present research, we investigated the influence of native-language adjective-noun word order on category accessibility for nouns and adjectives by comparing Portuguese speakers (in whose language nouns precede adjectives) with English speakers (in whose language adjectives precede nouns). In two studies, we presented participants with different numbers of verbal or pictorial stimuli, and subsequently they answered questions about noun- and adjective-conditioned frequencies. The results demonstrated a primacy effect of nativelanguage word order. Specifically, although both populations showed a speed advantage for noun-conditioned questions, this tendency was significantly stronger for Portuguese than for American participants. We discuss the important role of native-language syntax rules for the categorization and representation of information.     

Situating Ethical Behavior in the Nomological Network of Job Performance

Purpose

Our objective was to generate, define, and evaluate behavioral dimensions of ethical performance at work that are common across United States occupations.

Design/Methodology/Approach

This project involved three studies. Study 1 involved (a) qualitative review of published literature, professional codes of ethics, and critical incidents of (un)ethical performance and resulted in (b) behavioral dimensions and ethical performance rating scales. The second and third studies used a retranslation methodology to evaluate the ethical performance dimensions from Study 1. The behavioral dimensions were linked to the performance determinants (personal attributes) in Study 3.

Findings

Study 1 resulted in draft dimension definitions and rating scales for 10 ethical performance dimensions. In Studies 2 and 3, retranslation data provided strong support for 10 behavioral dimensions of ethical performance at work. Results from Study 3 shed light on possible relationships among the performance dimensions based on their underlying performance determinants.

Implications

Communicating an organization’s ethical standards to employees is important because some ethical breakdowns can be attributed to simply failing to recognize an ethical matter (in: DeCremer, Managerial ethics: Managing the psychology of morality, Routledge, New York, 2011). Definitions of ethical behavior in the workplace provide a tool for researchers, employers, and employees to communicate about ethical situations and a foundation for folding ethics into employee training and performance management.

Originality/Value

These studies provide a taxonomy of ethical performance at work that generalizes to a diverse array of occupations and industries, and dimensions and rating scales have value for performance management, training/curriculum development, job analysis, predictor development and/or validation, and additional research.

     

A taxonomic study of aggression in institutionalized delinquents

The taxonomy of aggressive behavior has been studied by many social scientists. In the present study this topic is approached empirically. A group of convicts were asked to quantify pairwise dissimilarity among aggressive social situations. The data obtained were processed by Multidimensional Scaling. The results show the necessity of taking into account 3 dimensions (justifiability, instrumentality and degree of involvement with the victim) in distinguishing among aggressive episodes. This finding is discussed in terms of cultural differences, and the usefulness of the perception of aggressive episodes as a basis for a taxonomic system is proposed.     

The Joyfully Sexual Infant in the Room: A Response to Frances Thomson-Salo and Campbell Paul

Some thoughts and material from clinical work and infant observations and from supervisions of infant observations are offered in response to Thomson-Salo and Paul’s assertion that infant sexuality is a critical aspect of the infant in him- or herself and in the infant–parent relationship. The distinct benefit for therapists that this position allows—a broadening access to and understanding of transference and countertransference experiences and thus to be able to offer something more in our thinking with patients, young and old—is further highlighted.     

Nonchildhood Sexual Abuse in Mexican American and Mexican College Students

This study aimed to assess and compare sexual abuse (SA) rates in female and male Mexican American college students (N = 514) and 2 samples of Mexican college students (N = 161 and N = 227). Participants responded to the Sexual Experiences Survey Victim Form (SES-SFV). SA prevalence and frequency rates were compared between sample groups for 3 categories of SA: nonchildhood SA (SA-NC, experienced since age 14), SA experienced in the previous 12 months (SA-12M), and lifetime self-labeled SA (SA-LL, any experience identified as abuse or rape by participants). Higher rates of self-reported SA were consistently found for Mexican versus U.S. samples. However, SA incidence was also consistently higher in older individuals and females; more recently experienced SA was reported at lower rates and with greater gender congruence than more distal SA; and variation between Mexican samples was roughly equal to variation between Mexican and U.S. samples. Findings show cross-national variation in SA rates.     

Bilingualism alters children's frontal lobe functioning for attentional control

Bilingualism is a typical linguistic experience, yet relatively little is known about its impact on children's cognitive and brain development. Theories of bilingualism suggest that early dual‐language acquisition can improve children's cognitive abilities, specifically those relying on frontal lobe functioning. While behavioral findings present much conflicting evidence, little is known about its effects on children's frontal lobe development. Using functional near‐infrared spectroscopy (fNIRS), the findings suggest that Spanish–English bilingual children (n = 13, ages 7–13) had greater activation in left prefrontal cortex during a non‐verbal attentional control task relative to age‐matched English monolinguals. In contrast, monolinguals (n = 14) showed greater right prefrontal activation than bilinguals. The present findings suggest that early bilingualism yields significant changes to the functional organization of children's prefrontal cortex for attentional control and carry implications for understanding how early life experiences impact cognition and brain development.     

What’s in a name? Intolerance of uncertainty,other uncertainty-relevant constructs,and their differential relations to worry and generalized anxiety disorder*

A number of studies have examined the association of intolerance of uncertainty (IU) to trait worry and generalized anxiety disorder (GAD). However, few studies have examined the extent of overlap between IU and other psychological constructs that bear conceptual resemblance to IU, despite the fact that IU-type constructs have been discussed and examined extensively within psychology and other disciplines. The present study investigated (1) the associations of IU, trait worry, and GAD status to a negative risk orientation, trait curiosity, indecisiveness, perceived constraints, self-oriented and socially prescribed perfectionism, intolerance of ambiguity, the need for predictability, and the need for order and structure and (2) whether IU is a unique correlate of trait worry and of the presence versus absence of Probable GAD, when overlap with other uncertainty-relevant constructs is accounted for. N = 255 adults completed self-report measures of the aforementioned constructs. Each of the constructs was significantly associated with IU. Only IU, and a subset of the other uncertainty-relevant constructs were correlated with trait worry or distinguished the Probable GAD group from the Non-GAD group. IU was the strongest unique correlate of trait worry and of the presence versus absence of Probable GAD. Indecisiveness, self-oriented perfectionism and the need for predictability were also unique correlates of trait worry or GAD status. Implications of the findings are discussed, in particular as they pertain to the definition, conceptualization, and cognitive-behavioral treatment of IU in GAD.     

Workplace Family Support,Parental Satisfaction,and Work–Family Conflict: Individual and Crossover Effects among Dual‐Earner Couples

Workplace family support has been regarded as a factor that helps reduce individuals' work to family conflict (WFC). How this support translates into families' functioning is still to be determined. In this study, we used a systems perspective to examine (a) how perceptions of workplace family support affect parental satisfaction and consequently reduce WFC and (b) how the perception of support affects partners' parental satisfaction and WFC in dual‐earner couples. A two‐wave dyadic data set of dual‐earner couples with preschool‐aged children (N = 90) was used, and the actor‐partner interdependence mediation model (APIMeM) was applied. Results showed that controlling for WFC, working hours, number and age of children, mothers' perceptions of workplace family support (time 1) had indirect effects, through mothers' parental satisfaction (time 1), on their own levels of WFC (time 2) as well as on their partners' levels of WFC (time 2). Fathers' perceptions of workplace family support (time 1) had a direct effect on fathers' parental satisfaction (time 1) and on fathers' WFC (time 2). These results suggest that in addition to boosting parental well‐being, perceptions of a supportive workplace may help reduce the level of WFC for both direct recipients of support and their partners, in particular when support is experienced by mothers, and when these mothers experience heightened parental satisfaction.
