Effects of Target Person Expression on Ethnic Prejudice Toward Middle Easterners and Hispanics

Research on implicit prejudice suggests that target person judgments may be affected by unintentional, but well‐learned, cognitive associations. Ethnicity, gender, and smiling or nonsmiling expression were varied as cues in White college students' perception tasks. The results of a factorial experiment are included as well as a discussion of the implications. La investigación sobre prejuicios implícitos sugiere que los juicios del individuo en cuestión pueden ser afectados por asociaciones cognitivas involuntarias, pero bien aprendidas. Se variaron la etnicidad, el género y la expresión sonriente o carente de sonrisa como entradas para las pruebas de percepción de estudiantes universitarios Blancos. Se incluyen los resultados de un experimento factorial, además de una discusión sobre las implicaciones.     

Classical conditioning of autonomic fear responses is independent of contingency awareness

The role of contingency awareness in classical conditioning experiments using human subjects is currently under debate. This study took a novel approach to manipulating contingency awareness in a differential Pavlovian conditioning paradigm. Complex sine wave gratings were used as visual conditional stimuli (CS). By manipulating the fundamental spatial frequency of the displays, we were able to construct pairs of stimuli that varied in discriminability. One group of subjects was given an "easy" discrimination, and another was exposed to a "difficult" CS+ and CS-. A 3rd group was exposed to a stimulus that was paired with the unconditional stimulus (UCS) 50% of the time and served as a control. Skin conductance response (SCR) and continuous UCS expectancy data were measured concurrently throughout the experiment. Differential UCS expectancy was found only in the easy discrimination group. Differential SCRs were found in the easy discrimination group as well as in the difficult discrimination group, but not in the 50% contingency control. The difficult discrimination group did not exhibit differential UCS expectancy but did show clear differential SCR. These observations support a dual process interpretation of classical conditioning whereby conditioning on an implicit level can occur without explicit knowledge about the contingencies.

Lesions of the rat nucleus basalis magnocellularis disrupt appetitive-to-aversive transfer learning

Rats with selective lesions of the nucleus basalis magnocellularis (NBM) and sham-lesion control animals were tested in an operant appetitive-to-aversive transfer task. We hypothesized that NBM lesions would not affect performance in the appetitive phase, but that performance would be impaired during subsequent transfer to the aversive phase of the task. Additional groups of NBM lesion and control rats were tested in the avoidance condition only, where we hypothesized that NBM lesions would not disrupt performance. These hypotheses were based, on the argument that the NBM is not necessary for simple association learning that does not tax attention. Both the appetitive phase of the transfer task and the avoidance only task depend only on simple associative learning and are argued not to tax attention. Consequently, performance in these tasks was predicted to be spared following NBM lesions. Complex, attention-demanding associative learning, however, is argued to depend on the NBM. Performance, in the aversive phase of the transfer task is both attentionally demanding and associatively more complex than in either the appetitive or aversive tasks alone; thus, avoidance performance in the NBM lesion group was predicted to be impaired following transfer from prior appetitive conditioning. Results supported our hypotheses, with the NBM lesion group acquiring the appetitive response normally, but showing impaired performance following transfer to the aversive conditioning phase of the transfer task. Impairments were not attributable to disrupted avoidance learning per se, as avoidance behavior was normal in the NBM lesion group tested in the avoidance condition only.     

Job‐Seeker Reactions to Selection Process Information in Job Ads

Using a policy‐capturing methodology, the current study examines if and to what extent individuals utilize selection process information contained in job ads in making evaluations of organizational attractiveness and decisions to apply. Results show both indirect and direct evidence that individuals do attend to and use these cues when presented in job ads in making initial job‐pursuit evaluations. Additionally, the results are consistent with a model derived from the organizational justice literature suggesting that perceptions of selection procedures' measurement accuracy may drive the observed effects. Specifically, ratings of organizational attractiveness and intentions to apply were significantly associated with perceptions of a given selection method's assessment accuracy for those ads that specified its use. Policy‐capturing results also show direct evidence that participants attend to and rely on selection process information in job ads to make job‐pursuit evaluations, and that perceptions of measurement accuracy are related to the degree to which, and how those cues are utilized. Research and applied implications are discussed.     

Transformational consumption choices: building an understanding by integrating social identity and multi‐attribute attitude theories

• Transformational value offerings result when marketers bundle products, services, and experiences in ways that provide consumers with opportunities to alter who they are. Examples include universities, healthcare providers, travel and leisure services, and many other businesses that guide individuals to change in some desired and lasting way. Pine and Gilmore ( 1999 ) predict that in the emerging economy “…transformation offerings will emerge across almost every industry that today views itself as part of the service sector” (p. 168). By definition, transformational value offerings involve identity development. Thus, it makes sense to use identity related variables to explain transformational value offering choices. This paper tests a model merging social identity theory and multi‐attribute attitude modeling to better understand factors predicting consumers' intentions to select a transformational value offering. A survey sample of United States Army Reserve recruits was used to test the integrated model. Results show that identity‐related perceptions form the basis for evaluating the value offering's benefits and intentions to adopt the offering. The prospective consumer also considers whether his or her self‐concept can accommodate that role. The proposed blending of social identity and multiattribute attitude models provides a promising framework for understanding and investigating consumers' choices to adopt transformational value offerings.

The Attitude–Behavior Relationship: A Test of Three Models of the Moderating Role of Behavioral Difficulty1

The moderating role of behavioral difficulty in the attitude–behavior relationship remains a controversial topic in social psychology. Previous research has been unclear in establishing the direction of this moderation, and 3 theoretical models have been proposed: positive and linear; negative and monotonic; and quadratic. The current paper reports analyses of survey data from 5 different studies that afford measures of environmental attitude, behavior, and behavioral difficulty. Across these studies, we found a substantial and unmoderated average attitude–behavior relationship (r = .54). The data also show that the attitude–behavior relationship is weaker for extremely easy and extremely difficult behaviors. Additional analyses suggest, however, that these reductions in the attitude–behavior relationship are probably because of methodological reasons.     

Some fear-potentiating effects of fluprazine hydrochloride in mice

The fear-potentiating effects of fluprazine hydrochloride were explored in a series of five experiments. The drug was found to strongly inhibit entry into a novel open field, exploration of a complex maze, or approach to a novel object placed in the animal's home cage. Time sampling techniques were used to assess drug effects on frequencies of immobility, activity, and grooming and rearing responses prior to and for 70 min after footshock. There were no group differences during the 10 min immediately following shock but the groups diverged steadily in immobility, activity, and grooming for the remainder of the observations. Post-shock activity and grooming responses increased steadily towards baseline values among control mice but remained at low levels or declined among drug-treated mice. Immobility responses declined steadily among control mice but increased substantially among the fluprazine-treated mice throughout post-shock observations. Pairs of male mice treated with fluprazine were also found to maintain greater intermouse distances in a novel linear runway than pairs of undrugged adult males, juvenile males, or male-female pairs. It is suggested that fluprazine hydrochloride both potentiates fear and alters its time course in addition to interfering in some way with normal olfactory processes.
