Absence of hardly pursued updating in a running memory task

In a running memory span task, the participants are presented with a list of items (e.g. numbers or words) of an unknown length, because this length varies from trial to trial. In one variation of the procedure the participants must report a certain fixed number of items (e.g. four) from the end of the list. According to Morris and Jones (British Journal of Psychology, 81, 111-121, 1990), the recalled items must be updated in memory as the presentation of the list progresses. Ruiz, Elosúa and Lechuga (The Quarterly Journal of Experimental Psychology, 5, 887-905, 2005) noted that an active strategy implies an inhibition in memory of the final discarded items, and did not find results which supported this hypothesis. The aim of this study is to check whether or not participants adopt an active processing strategy in extreme conditions. Experiment 1 uses catch trials, which induce the participants not to discard the first items of the lists, and also short lists (of 4, 7, 8, 9 and 10 items); these could be considered optimal conditions for updating. However, it should also be pointed out that with an upper limit of 10 items per list, participants could try to memorise the whole list in most of the trials. One way to discourage this strategy is including lists well over span (e.g. 14-26 items). The purpose of Experiment 2 was to analyse the 10-item lists in two conditions: within a context of much longer lists (well over span) in most of the trials and within a context of shorter lists (data of Experiment 1). Results in both experiments, from the analysis of location errors, indicate that even in these conditions the participants do not seem to carry out the supposed active updating of the memory set.     

For Better and Worse: Social Influences on Coronary Heart Disease Risk

From the neighborhoods we live in to those we marry, other people are a part of our everyday lives. Mounting evidence suggests that these social factors constitute risk and resilience influences for coronary heart disease (CHD). The current aim is to summarize the literature into four representative categories relating to CHD risk: social environments, social roles, social resources, and close relationships. The argument is made that these factors moderate and mediate stress and associated physiological responses constituting a psychosomatic pathway to disease.     

Taxometric analyses of borderline personality features in a large-scale male and female offender sample

Few studies to date have examined the extent to which borderline personality features are best construed as representing an underlying dimension or a discrete class or taxon. The authors conducted taxometric analyses using a large-scale sample of male (n=787) and female (n=368) prison inmates who had completed the Personality Assessment Inventory (L. C. Morey, 2007). Analyses based on the 4 subscales of the Borderline Features Scale offered compelling support for a dimensional structure in both the full sample and the female subsample--even after controlling for the potentially confounding effects of negative response distortion. Theoretical and pragmatic implications of these findings are reviewed.     

Influence of articulation rate on two memory tasks in young and older adults

This study investigated the relation between phonological loop functioning and age. Phonological loop is a time-based subsystem of the Working Memory Model of Baddeley and Wilson, which uses rehearsal of information as an active process to avoid phonological decay. Performance differences were examined between young and older adults in two speech-based memory tasks, such as the immediate serial recall of words and the Digit Ordering Task. Analysis showed that performance on both tasks was lower for the older group. Articulation rate was also measured to test the hypothesis that the impairment of some cognitive functions in adults can be associated to their slowness or the greater time needed by older adults for the rehearsal process. A significant negative correlation was found for articulation rate with age. When the effect of articulation rate on Serial Recall and Digit Ordering Tasks was partialled out, the difference between the two groups was eliminated.     

The Effects of Images of African American Women in Hip Hop on Early Adolescents’ Attitudes Toward Physical Attractiveness and Interpersonal Relationships

This qualitative study was designed to identify African American early adolescents’ subjective meanings of African American women’s sexuality through an examination of Stephens & Phillips (2003) sexual images—the Diva, Gold Digger, Freak, Dyke, Gangster Bitch, Sister Savior, Earth Mother, and Baby Mama. These eight sexual images both inform and reflect beliefs about African American women’s physical attractiveness. Interpersonal relationship decision making processes also were influenced by these conceptual frameworks of African American women’s sexuality. Findings from this study are important given the tendency of previous researchers to ignore race and intraethnic variations in studies of beliefs about attitudes toward sexuality.     

Temperamental dimension and anxiety problems in a clinical sample of three- to six-year old children: a study of variables

In the last few years, many researchers have studied the presence of common dimensions of temperament in subjects with symptoms of anxiety. The aim of this study is to examine the association between temperamental dimensions (high negative affect and activity level) and anxiety problems in clinical preschool children. A total of 38 children, ages 3 to 6 years, from the Infant and Adolescent Mental Health Center of Girona and the Center of Diagnosis and Early Attention of Sabadell and Olot were evaluated by parents and psychologists. Their parents completed several screening scales and, subsequently, clinical child psychopathology professionals carried out diagnostic interviews with children from the sample who presented signs of anxiety. Findings showed that children with high levels of negative affect and low activity level have pronounced symptoms of anxiety. However, children with anxiety disorders do not present different temperament styles from their peers without these pathologies.     

FUNCTIONAL ANALYSIS AND TREATMENT OF SELF‐INJURY IN A CAPTIVE OLIVE BABOON

Self‐injurious behavior (SIB), such as self‐biting and head banging, has been reported to occur in approximately 10% of captive, individually housed nonhuman primates. Accounts of the etiology of SIB in primates range from ecological to physiological. However, to date, no research has examined the possible influence of social consequences delivered by handlers and keepers in the maintenance of SIB in this population. The current study investigated the effects of social contact as a potentially reinforcing consequence for the SIB displayed by an olive baboon (Papio hamadryas anubis). Results indicated that the behavior was maintained by attention from humans. As treatment, reinforcement was arranged for an appropriate alternative response, resulting in increases in the appropriate alternative behavior and decreases in SIB.     

Measuring fluid intelligence on a ratio scale: Evidence from nonverbal classification problems and information entropy

Drawing on the g factor and information theory literatures, the relationship between the four subtests of the Culture-Fair Intelligence Test (CFIT) and the entropy of the Ruiz Absolute Scale of Complexity Management (R-ASCM) was investigated. In results based on data collected from 186 university students, the entropy of the R-ASCM mostly loads the first principal component extracted from the CFIT subtests and shows a corresponding strong relationship with the item difficulty of the R-ASCM. Because entropy is a ratio scale of complexity— with a true zero and units called bits—these findings suggest that entropy is the right vehicle for measuring the information contained in nonverbal intelligence tests.     

The perception of time heals all wounds: temporal distance affects willingness to forgive following an interpersonal transgression

Prior research has assessed the temporal unfolding of forgiveness and found that forgiveness becomes more likely as time distances the victim from the transgression. These findings lend credence to the axiom "time heals all wounds." This research examines the effect of time perception on forgiveness of others by experimentally manipulating temporal distance. In Experiment 1, respondents reported greater willingness to forgive the transgressor when more time had elapsed since the transgression. Experiments 2 and 3 determined the influence of subjective temporal distance on willingness to forgive. Participants who perceived a hypothetical (Experiment 2) or real (Experimental 3) transgression to be farther away in time were more willing to forgive the target than were participants who perceived the event to be temporally closer. Results suggest that temporal appraisals of an event are central to the forgiveness process.
