Measuring attention in the hemispheres: the lateralized attention network test (LANT)

The attention network test (ANT) is a brief computerized battery measuring three independent behavioral components of attention: Conflict resolution (ability to overcome distracting stimuli), spatial Orienting (the benefit of valid spatial pre-cues), and Alerting (the benefit of temporal pre-cues). Imaging, clinical, and behavioral evidence demonstrate hemispheric asymmetries in these attentional networks. We constructed a lateralized version of the ANT (LANT), with brief targets flashed in one or the other visual hemifield. We also modified the tests by including invalid spatial cues in order to measure the cost component of Orienting. In a series of experiments, we investigated the efficiency of the attention networks separately in each hemisphere. Participants exhibited significant estimates of all networks measured by the LANT, comparable to the ANT. The three networks were represented in each hemisphere separately and were largely comparable across the two hemispheres. We suggest that the LANT is an informative extension of the original ANT, allowing for measurement of the three attention networks in each hemisphere separately.     

Cognitive interference and aging: insights from a spatial stimulus-response consistency task

One hundred and thirty-one adults belonging to four age groups (19-26, 50-59, 60-69 and 70-82 years) performed a spatial stimulus-response consistency task in which the response dimension (left or right) overlapped relevant and irrelevant stimulus dimensions. The influence of the irrelevant stimulus dimension on response time was significantly greater in the middle age groups than among 19-26 year-olds, and significantly greater in the highest age group than in any other. This pattern persisted when allowance was made for a significant age-related increase in processing time (measured as reaction time in a single-stimulus, single-response task). It is concluded that in tasks of the kind used, the elderly resist interference from the irrelevant information less easily than do younger persons. Interestingly, comparison of Vincentized quintiles suggested that the effect of the irrelevant stimulus dimension decreased with increasing response time among 19-26 year-olds, but increased with response time among 70-82 year-olds.     

Unresolved anger and sadness: Identifying vocal acoustical correlates

The authors conducted 2 studies to identify the vocal acoustical correlates of unresolved anger and sadness among women reporting unresolved anger toward an attachment figure. In Study 1, participants (N = 17) were induced to experience and express anger then sadness or sadness then anger. In Study 2, a 2nd group of participants (N = 22) underwent a relationship-oriented, emotion-focused analogue therapy session. Results from both studies showed that, relative to emotionally neutral speech, anger evoked an increase in articulation rate and in mean fundamental frequency (F0) and F0-range, whereas sadness evoked an increase in F0-perturbation. Both F0 and F0-range were larger for anger than for sadness. In addition, results from the mood-induction-procedure study revealed 2 Emotion×Order interactions. Whereas variations in amplitude range suggested that anger evoked less physiological activation when induced after sadness, variations in F0-perturbation suggested that sadness evoked more physiological activation when induced after anger. These findings illustrate the feasibility of using acoustical measures to identify clients' personally and clinically meaningful emotional experiences, and shifts between such emotional experiences, in the context of psychotherapy.

Human–Android Interaction in the Near and Distant Future

ABSTRACT— In this article, a psychologist and an artificial-intelligence (AI) researcher speculate on the future of social interaction between humans and androids (robots designed to look and act exactly like people). We review the trajectory of currently developing robotics technologies and assess the level of android sophistication likely to be achieved in 50 years time. On the basis of psychological research, we consider obstacles to creating an android indistinguishable from humans. Finally, we discuss the implications of human–android social interaction from the standpoint of current psychological and AI research and speculate on the novel psychological issues likely to arise from such interaction. The science of psychology will face a remarkable new set of challenges in grappling with human–android interaction.     

Affiliative behaviour of approach- and avoidance-motivated subjects in fear and anxiety situations

This study examined the effects of fear- and anxiety-inducing situations on affiliative behaviour of approach-oriented and avoidance-oriented Ss. Two samples of high school and university students were utilized to examine the following hypotheses: a) In fear situations, affiliative behaviour will increase in both approach- and avoidance-oriented subjects; b) in anxiety situations, affiliative behaviour will increase in approach-oriented subjects and decrease in avoidance-oriented ones. The results confirmed the hypotheses for a verbal criterion of affiliative behaviour, and partially for a behaviour criterion.     

Negative bodily self in suicide attempters

In the present study we investigated the relationship between suicidal behavior and aspects of bodily perception and parental care. Measures of bodily perception included measures of tactile sensitivity, body attitudes, and body experiences. Measures of parental care included parental bonding, negative and positive touch, and early maltreatment. One hundred and two adolescents (suicidal and nonsuicidal inpatients, and a control group) participated in the study. It was hypothesized that suicidal adolescents would (1) have higher tactile sensation thresholds, and more negative body attitudes and experiences; and (2) report less parental care, lower positive and higher negative parental touch, and higher parental maltreatment. It was also hypothesized that bodily sensitivity would mediate the relationship between suicidal tendencies and perceived negative early care. These hypotheses were confirmed. The role of a negative bodily self in suicidal behavior is proposed and discussed.     

Core self-evaluations and job and life satisfaction: the role of self-concordance and goal attainment

The present study tested a model explaining how the core self-evaluations (i.e., positive self-regard) concept is linked to job and life satisfaction. The self-concordance model, which focuses on motives underlying goal pursuit, was used as an explanatory framework. Data were collected from 2 samples: (a) 183 university students (longitudinal measures of goal attainment and life satisfaction were used) and (b) 251 employees (longitudinal measures of goal attainment and job satisfaction were utilized). In both studies, the core self-evaluations concept was positively related to goal self-concordance, meaning that individuals with positive self-regard were more likely to pursue goals for intrinsic and identified (value-congruent) reasons. Furthermore, in both studies, goal self-concordance was related to satisfaction (job satisfaction in Study 1 and life satisfaction in Study 2).     

When Gender Differences Surpass Cultural Differences in Personal Satisfaction with Body Shape in Israeli College Students

This study was designed to examine influences of gender and cultural background on participants satisfaction with body-shape. Participants were Jewish and Arab university students (104 men and 96 women), who completed the Figure Rating Scale (Fallon & Rozin, 1985). Discrepancy between current and ideal figures was used to measure body satisfaction. As in the U.S., women, in comparison with men, were significantly less satisfied with their bodies. They exaggerated the magnitude of thinness that they thought men desire. In contrast with U.S. findings, there were women as well as men, who indicated dissatisfaction with their bodies because they thought they were too thin. Contrary to our predictions, cultural background did not influence body satisfaction. However, gender and age produced significant differences in ratings.     

Creative thinking abilities and hemispheric asymmetry in schizotypal college students

Two groups of college students that scored high (N=25) and low (N=60) on a schizotypal personality index based on the Perceptual Aberration, Magical Thinking, and Schizotypal Personality Scales, were tested for hemisphericity using a dichotic listening task and completed the Torrance Test of Creative Thinking. The schizotypy scales correlated with high scores on the nonverbal portion of the creativity tests and with a left ear preference to dichotically presented verbal stimuli. The Torrance Test of Creative Thinking did not correlate, however, with hemispheric asymmetry. These results clarify the relationship between schizotypy and creating thinking abilities but fail in establishing the role of hemispheric asymmetry in the production of creative thinking ideas. This article is based on a portion of the first author’s dissertation at Wayne State University.     

Modifying automatic approach action tendencies in individuals with elevated social anxiety symptoms

Research suggests that social anxiety is associated with a reduced approach orientation for positive social cues. In the current study we examined the effect of experimentally manipulating automatic approach action tendencies on the social behavior of individuals with elevated social anxiety symptoms. The experimental paradigm comprised a computerized Approach Avoidance Task (AAT) in which participants responded to pictures of faces conveying positive or neutral emotional expressions by pulling a joystick toward themselves (approach) or by moving it to the right (sideways control). Participants were randomly assigned to complete an AAT designed to increase approach tendencies for positive social cues by pulling these cues toward themselves on the majority of trials, or to a control condition in which there was no contingency between the arm movement direction and picture type. Following the manipulation, participants took part in a relationship-building task with a trained confederate. Results revealed that participants trained to approach positive stimuli displayed greater social approach behaviors during the social interaction and elicited more positive reactions from their partner compared to participants in the control group. These findings suggest that modifying automatic approach tendencies may facilitate engagement in the types of social approach behaviors that are important for relationship development.
