Memory with and without awareness: performance and electrophysiological evidence of savings.

Event-related potentials (ERPs) recorded on the scalp were shown to be sensitive indicators of the strength of a memory trace on both implicit and explicit tests of memory. In explicit recognition tests, the amplitude of a positive potential identified as P300 was larger for "old" than for "new" words regardless of whether the subject categorized the items correctly. This effect, however, was statistically reliable only when the recognition memory (d') was relatively high. In contrast to ERPs, the reaction times in explicit recognition were sensitive to accuracy but not to repetition. In implicit tests, lexical decisions to repeated words were faster than to newly presented words. The magnitude of the repetition effect varied neither with elapsed time since the last repetition nor with the number of previous repetitions. In contrast, the P300 elicited by the same words were sensitive to both lag and recency of repetition, suggesting that they were influenced by the episodic memory strength of the items.     

Looking at pictures but remembering scenes.

Ss tend to remember close-up photographs as having had extended boundaries (Intraub & Richardson, 1989). Three alternate explanations were tested: object completion, distortion toward a perceptual schema, and normalization toward a prototypic view. In three experiments, 55-130 undergraduates viewed 16 close-up, prototypic, or wide-angle views of objects for 15 s each. Immediately or 48 hr later, they rated test pictures on a 5-point scale as "same", "closer up", or "father away." Results ruled out object completion because boundary extension occurred when the picture contained no incomplete objects. Immediate tests supported the perceptual schema hypothesis because all unidirectional distortions involved boundary extension. Delayed tests were more suggestive of a memory schema effect because wide-angle pictures yielded boundary restriction. A two-component model of picture processing is proposed.     

CAUCASIAN LESBIANS' USE OF PSYCHOTHERAPY: A Matter of Attitude?

Evidence suggests that a high proportion of lesbians seek psychological counseling. This study represents an empirical investigation of the disproportionate use of mental health services by lesbians, focusing on the hypothesis that lesbians place a greater value on psychotherapy than do nonlesbian women. Participants (100 lesbians and 309 nonlesbian women, 97% Caucasian) completed Surgenor's revision of the Attitudes Toward Seeking Professional Psychological Help Scale. Results indicate that the lesbian group had a significantly more positive attitude toward seeking psychological counseling than did the nonlesbian sample, regardless of whether or not they had experienced psychological counseling.     

TOWARD A FEMINIST UNDERSTANDING OF WOMEN AND POWER

Both psychologists and feminists believe power is an important and ubiquitous concept, yet its definition and scope eludes both groups. In this introduction to a special issue on women and power, we suggest three points to help organize and interpret research in the area. First, definitions of power should center around the distinction between "power-over," the domination and control of one person or group over another, and "power-to" or personal empowerment. Second, power can be analyzed at different levels—societal, organizational, interpersonal, and individual—and, importantly, these levels interact. Third, power differences frequently underlie what appear to be gender differences in behavior; as society is currently configured, power and gender are never independent. Although the articles in this special issue often ask more questions than they answer, the present volume adds a feminist perspective to the psychological study of power.     

By your attributions you shall be known: Consequences of attributional accounts for professional and gender identities

We demonstrate the power of a situated identity perspective for understanding the different attributional patterns of women and men in an academic setting and their differential experiences in the workplace. Two explanations for the gender difference found in attributions of success are considered. This difference may be due either to different identities being attributed to men and women employing the same explanations for success and failure, or to the inconsistency between actions that confirm a professional (academic) identity and women's gender identity. The results of this survey of senior social science faculty men support the latter explanation but not the former. An editorial acceptance was seen as more professional but less feminine than a rejection. In the eyes of senior colleagues, the modest account of success, typical of women academics, enhances femininity but detracts from professionalism. The self-serving account typical of men makes the offerer appear less feminine but more professional. Thus in their situated identity claims, successful academic women, but not men, must choose between their professional and gender identities. Despite the movement of women into university social science positions, the role of academic has a masculine face.Order of authors was determined by a coin toss.     

Reflections on group psychotherapy with eating-disordered patients

This paper addresses some of the dynamics, resistances, and transference and countertransference considerations in group psychotherapy with eating disordered patients. Several resistances are delineated, including guilt over being helped, the recreation of early problems around control and forced feeding, and withdrawal as a defensive operation. A brief vignette is presented which highlights the demand on the part of the therapist as well as the patient to contain and manage feelings rather than acting on them. Lastly, the author argues that group participation helps the patient to identify, articulate, and accept feelings and to promote assertiveness.This paper is based on a presentation given at the Training Institute for Mental Health on May 11, 1991.     

Simultaneous conditioning in honeybees (Apis mellifera).

Honeybees (Apis mellifera) were classically conditioned with odor as conditioned stimulus (CS), sucrose as unconditioned stimulus (US), and proboscis extension as response. The purpose of Experiment 1 (Ns = 26 and 27) was to look for facilitation of forward conditioning by CS-US overlap, but rapid conditioning without overlap left little room for improvement. In 2 further experiments, CS and US were simultaneous, and response to odor alone was measured in subsequent tests. In Experiment 2, a Simultaneous group (N = 25) responded more to the training odor than did an Unpaired control group (N = 25). In Experiment 3, a differentially conditioned Simultaneous group (N = 29) responded more to an odor paired with sucrose in training (S+) than to an odor presented alone (S-). The implications of the results for the problem of the role of amount of reward in honeybee learning are considered.     

Search behavior in various breeds of adult dogs (Canis familiaris): object permanence and olfactory cues.

Human analog tests of object permanence were administered to various breeds of adult dogs (Canis familiaris). Experiment 1 showed that the performance of terriers, sporting, and working dogs did not differ. Dogs succeeded in solving invisible displacement problems, but performance was lower than in visible displacement tests. Familiarity with the task had some influence because invisible displacement tests were more successful if they were preceded by visible displacement tests. In Experiment 2, odor cues from the target object and the hiding screens were available or were masked. Results confirmed that success was lower in invisible than in visible displacement tests and that these problems were solved on the basis of representation of visual information rather than on the basis of olfactory cues or of local rule learning. Dogs are compared with other species that display Stage 6 object permanence.
