Objects and events in the attentional blink

When two visual targets, T1 and T2, are presented in rapid succession, detection or identification of T2 is almost universally degraded by the requirement to attend to T1 (the attentional blink, or AB). One interesting exception occurs when T1 is a brief gap in a continuous letter stream and the task is to discriminate its duration. One hypothesized explanation for this exception is that an AB is triggered only by attention to a patterned object. The results reported here eliminate this hypothesis. Duration judgments produced no AB whether the judged duration concerned a short gap in the letter stream (Experiment 1) or a letter presented for slightly longer than others (Experiment 2). When identification of an identical longer letter T1 was required (Experiment 3), rather than a duration judgment, the AB was reestablished. Direct perceptual judgments of letter streams with gaps embedded showed that whereas brief gaps result in the percept of a single, briefly hesitating stream, longer gaps result in the percept of two separate streams with a separating pause. Correspondingly, an AB was produced in Experiment 4, when participants were required to judge the duration of longer T1 gaps. We propose that, like spatially separated objects, temporal events are parsed into discrete, hierarchically organized events. An AB is triggered only when a new attended event is defined, either when a long pause creates a new perceived stream (Experiment 4) or when attention shifts from the stream to the letter level (Experiment 3).     

Auditory memory and the irrelevant sound effect: Further evidence for changing-state disruption

Four experiments investigate the hypothesis that irrelevant sound interferes with serial recall of auditory items in the same fashion as with visually presented items. In Experiment 1 an acoustically changing sequence of 30 irrelevant utterances was more disruptive than 30 repetitions of the same utterance (the changing-state effect; Jones, Madden, & Miles, 1992) whether the to-be-remembered items were visually or auditorily presented. Experiment 2 showed that two different utterances spoken once (a heterogeneous compound suffix; LeCompte & Watkins, 1995) produced less disruption to serial recall than 15 repetitions of the same sequence. Disruption thus depends on the number of sounds in the irrelevant sequence. In Experiments 3a and 3b the number of different sounds, the "token-set" size (Tremblay & Jones, 1998), in an irrelevant sequence also influenced the magnitude of disruption in both irrelevant sound and compound suffix conditions. The results support the view that the disruption of memory for auditory items, like memory for visually presented items, is dependent on the number of different irrelevant sounds presented and the size of the set from which these sounds are taken. Theoretical implications are discussed.     

Involving family members in the treatment of OCD

This review focuses on previous research with families of adults and children with obsessive-compulsive disorder (OCD). Three primary areas of research are covered: (i) characteristics of family members and the family environment; (ii) the prediction of treatment response based on family variables; and (iii) the inclusion of family members in treatment. Much of the research supports a hypothesized model of family response to symptoms of OCD that ranges on a continuum from overly accommodating to overly antagonistic. Further research indicates that responses at either extreme of this continuum are associated with poorer response to both exposure and response prevention (ERP) and pharmacotherapy. Finally, results of preliminary treatment outcome studies suggest that family-based interventions aimed at reducing such responses and/or including family members in ERP as coaches or co-therapists may enhance patients' response to treatment. Based on current theory and research, suggestions for future research and general recommendations for involving family members in treatment are made.     

Cognitive therapy for obsessive-compulsive disorder

A multiple baseline across subjects design was used to test the efficacy of cognitive therapy for obsessive–compulsive disorder (OCD). Six people with OCD received 10–18 sessions of weekly, outpatient cognitive therapy. Assessment included both structured interviews and diary data. For three to four of the six patients, stable baseline periods were followed by reductions of symptoms during intervention. Two clients met stringent criteria for Jacobson and Truax's (J. Consulting Clin. Psychol. 59 (1991) 12) recovered status at posttest according to the Yale–Brown Obsessive–Compulsive Scale (Arch. Gen. Psychiatry 46 (1989) 1006). For the group, large pretest–posttest effect sizes were found.     

Pronouns in marital interaction

Recent studies in social psychology have found that the frequency of certain words in people's speech and writing is related to psychological aspects of their personal health. We investigated whether counts of "self" and "other" pronouns used by 59 couples engaged in a problem-solving discussion were related to indices of marital health. One spouse in each couple had a diagnosis of obsessive-compulsive disorder or panic disorder with agoraphobia; 50% of the patients and 40% of their spouses reported marital dissatisfaction. Regardless of patients' diagnostic status, spouses who used more second-person pronouns were more negative during interactions, whereas those who used more first-person plural pronouns produced more positive problem solutions, even when negative behavior was statistically controlled. Moreover, use of first-person singular pronouns was positively associated with marital satisfaction. These findings suggest that pronouns used by spouses during conflict-resolution discussions provide insight into the quality of their interactions and marriages.     

Perceptual asymmetries in normal children and children with attention deficit/hyperactivity disorder

Perceptual asymmetries in normal right-handed children (7-12 years of age) and children with attention deficit/hyperactivity disorder (ADHD), combined type, were investigated using various chimeric stimuli in free-viewing conditions. In the face-matching task, participants indicated which of two symmetrical face chimeras more closely resembled the original; in the chimeric faces task, participants indicated which of a pair of faces appeared happier; and in the grey scales task participants indicated which of two shaded rectangles appeared to be darker overall. Leftward biases were found for normal children with no effects of age. Contrary to expectations, normal leftward biases were also found for ADHD children in the face-matching and the chimeric faces tasks; however, a significant leftward bias was not observed in the grey scales task. The absence of anomalous perceptual bias in ADHD children on these purely perceptual tasks, suggests that anomalous perceptual asymmetries observed in other tasks (line bisection and cancellation tasks) may have been confounded by the motor response, and/or the explicit spatial components of those tasks.     

The Time-Urgency Component of the Type A Behavior Pattern: Time Pressure and Performance1

We investigated the effects of time pressure on the performance of Type A and Type B individuals. We predicted that Type As would perform more poorly than Type Bs on an anagram task during a timed condition, but not during an untimed condition. Subjects were 40 female undergraduates and the Jenkins Activity Survey was used to measure Type A behavior. The results confirmed our hypothesis. Type As made significantly more errors than Type Bs when timed, but not when untimed. Implications of these findings and the time-urgency component of the Type A behavior pattern are discussed.     

Self-Presentational Motivations and Personality Differences in Self-Esteem

ABSTRACT  This article discusses the interpersonal motivations associated with different levels of self-esteem. Although self-esteem literally refers to an intrapsychic attitude, we propose that self-esteem scales often measure a self-presentational orientation. High self-esteem scores are associated with a tendency to present oneself in a self-enhancing fashion that is characterized by willingness to accept risks, focus on outstandingly good qualities, strategic ploys, and calling attention to self. Low self-esteem scores are associated with a tendency to present oneself in a self-protective fashion that is characterized by unwillingness to accept risks, focus on avoiding outstandingly bad qualities, avoidance of many strategic ploys, and reluctance to draw attention to self. Considerable evidence shows that most people rate themselves as above average on self-esteem scales; relatively few people score below any self-esteem scale's conceptual midpoint. Review of past literature yields the following conclusions: (a) Low scores on self-esteem scales are typically the result of neutral and intermediate rather than self-derogatory responses to scale items; (b) behavioral correlates of measured self-esteem sometimes depend on self-presentational variables such as audience presence; and (c) many past findings with self-esteem scales may be interpretable in self-presentational terms.
