Detecting symmetry and faces: Separating the tasks and identifying their interactions

Face and symmetry processing have common characteristics, and several lines of evidence suggest they interact. To characterize their relationship and possible interactions, in the present study we created a novel library of images in which symmetry and face-likeness were manipulated independently. Participants identified the target that was most symmetric among distractors of equal face-likeness (Experiment 1) and identified the target that was most face-like among distractors of equal symmetry (Experiment 2). In Experiment 1, we found that symmetry judgments improved when the stimuli were more face-like. In Experiment 2, we found a more complex interaction: Image symmetry had no effect on detecting frontally viewed faces, but worsened performance for nonfrontally viewed faces. There was no difference in performance for upright versus inverted images, suggesting that these interactions occurred on the parts-based level. In sum, when symmetry and face-likeness are independently manipulated, we find that each influences the perception of the other, but the nature of the interactions differs.     

THE VALIDITY OF THE POTENTIAL LEVEL VIA LISTENING COMPREHENSION: A CAUTIONARY NOTE

Historical background and relevant research were examined to determine whether the commonly recommended procedure of determining the reading potential level via listening comprehension is valid in the primary grades. No support was found for the unstated assumptions necessary for this procedure's validity. And three major studies conclusively revealed that use of this procedure to identify children for remedial instruction would drastically over‐refer and would include vast numbers of primary grade children progressing normally in learning to read. Based on this evidence, it was concluded that listening comprehension definitely not be used to determine the reading potential level in grades 1‐3.     

Alexithymia and the interpretation of emotion-relevant information

Abstract

This study examined the relationship between alexithymia and (a) hemis-patial bias; (b) the accuracy of interpreting emotion-relevant information; and (c) the style of interpreting emotion-relevant information. Subjects were 137 college students. Alexithymia was measured using the Toronto Alexithymia Scale. Hemispatial bias was measured using a free-vision chimeric face task. Interpretations of emotion-relevant information were assessed using the Profile of Nonverbal Sensitivity (PONS) and a second instrument designed for this study called the Emotional Story Test (EST). Although high levels of alexithymia were associated with hemispatial bias, alexithymia was not associated with the accuracy of subjects' interpretations. In contrast, alexithymia was associated with low ratings of emotional intensity and with subjects' inclinations to choose angry and dominant interpretations.     

Directed remembering: Subliminal cues alter nonconscious memory strategies

Much research on memory function has focused on changes in recognition performance brought about by differences in the processes engaged during encoding. In most of this work, participants either receive explicit instructions to remember particular items or they perform orienting (i.e., encoding) tasks that support different levels of memory performance. In daily life, however, the retention or dismissal of information often occurs without conscious intent, thereby suggesting an alternative, nonconscious route through which purposive remembering and forgetting can occur. Based on this line of reasoning, we speculated that recognition performance in a standard item-based forgetting paradigm may be moderated by subliminal cues that trigger the automatic activation of different mnemonic strategies. We report the results of two experiments that supported this prediction. In each experiment, the basic item-based forgetting effect was replicated, but via the subliminal presentation of “remember” and “forget” cues. In addition, cue-dependent differences in memory performance were traced to the operation of a covert rehearsal mechanism during encoding. We consider the implications of these findings for the non-conscious operation of memory processes in everyday life.     

Naming without knowing and appearance without associations: Evidence for constructive processes in semantic memory?

Abstract

This study describes a patient (SE) with temporal lobe injury resulting from Herpes Simplex Encephalitis, who displayed a previously unreported impairment in which his knowledge of associative and functional attributes of animals was disproportionately impaired by comparison with his knowledge of their sensory attributes (including their visual properties and characteristic sounds). His knowledge of man-made objects was preserved. A striking aspect of the present case was that the patient remained able to name many animals from their pictures, despite making gross errors in generating associative information about these same animals. This suggests that a semantic representation incorporating stored sensory knowledge may be sufficient for naming (at least for biological categories) and associative information may be unnecessary. Semantic knowledge may normally incorporate more information than is necessary for identification. SE's errors were found to be confabulatory and reconstructive in nature and it is argued that this aspect of his performance challenges passive conceptions of semantic memory couched in terms of a catalogue of stored representations. It is proposed that the patient's disorder affects a dynamic, constructive, and inferential component of his knowledge base, and that this component is sensitive to semantic category.     

Hierarchical elaboration in the conceptual structures of vietnam combat veterans

Abstract

Sixty male Vietnam combat veterans, 30 hospitalized for post-traumatic stress disorder (PTSD) and 30 with no PTSD or other psychiatric disorder, sorted and labeled their life events into numeric matrices (repertory grids). Through hierarchical-classes analysis of a subject's matrix, we could compare the hierarchical level (elaboration) of the subject's constructs of a negative combat event with the hierarchical levels of other subjects' constructs of negative combat events and with the subject's precombat life event construction. As predicted, the level of construct elaboration was virtually identical for the two groups for precombat non-trauma-related events but was reduced in the PTSD group for the negative combat event. In addition, the Pythagorean distance scores of the PTSD group indicated less conceptual distance between the negative combat event and negative life events after Vietnam compared with the non-PTSD group's scores. Patients with PTSD rated negative life events more extremely (fewer “shades of gray” ratings) than did the non-PTSD group, especially life events that occurred after Vietnam.     

The unbearable articulatory nature of naming: on the reliability of word naming responses at the item level

Single-word naming is one of the most widely used experimental paradigms for studying how we read words. Following the seminal study by Spieler and Balota (Psychological Science 8:411–416, 1997), accounting for variance in item-level naming databases has become a major challenge for computational models of word reading. Using a new large-scale database of naming responses, we first provided a precise estimate of the amount of reproducible variance that models should try to account for with such databases. Second, by using an item-level measure of delayed naming, we showed that it captures not only the variance usually explained by onset phonetic properties, but also an additional part of the variance related to output processes. Finally, by comparing the item means from this new database with the ones reported in a previous study, we found that the two sets of item response times were highly reliable (r = .94) when the variance related to onset phonetic properties and voice-key sensitivity was factored out. Overall, the present results provide new guidelines for testing computational models of word naming with item-level databases.     

Behavioral responses to anxiety: Self-reliance,counterdependence, and overdependence

This article builds on the original foundations of attachment theory and traces the strategies for achieving felt security into the adulthood years. The theoretical case is made for a link between a secure, self-reliant strategy and healthy adulthood functioning. This self-reliant strategy counteracts the health risk factors of social isolation and separation in human relationships. The strategy results in an enduring personality characteristic of self-reliance, a paradoxical pattern of behavior characterized by flexibility and bonding in relationships which appears rather autonomous. This article proposes a work-related measure of self-reliance which also incorporates the two insecure, unhealthy strategies for achieving felt security. These strategies are the dismissing strategy, which results in a counterdependent pattern of behavior, and the preoccupied strategy, which results in an overdependent behavior pattern. Preliminary reliability and validity data concerning the Self-Reliance Inventory are presented.
