Effects of situational cues on prism-induced aftereffects

A test was made of the hypothesis that external stimuli present during exposure to lateral displacement of the visual field can serve as situational cues whose presence or absence will influence the magnitude of aftereffects manifested subsequent to adaptation resulting from the exposure. The results indicated that the relative aftereffects were significantly greater when thenondisplacing goggles were worn during the periods in which aftereffect measurements were taken than was the case when they were removed during these test periods. The finding that manipulation of certain cues, i.e., the restriction of the visual field, weight, etc., of the goggles, associated with the adaptation period can in part determine the size of observed aftereffects provides evidence in support of the notion that aftereffects can be conditioned to precisely given constellations of stimuli In addition, the need for caution in conceptualizing aftereffects as simply the persistence of adaptive shifts once visual displacement has been terminated is suggested.     

Interactive effects of life experience and situational cues on aggression: The weapons priming effect in hunters and nonhunters

Recent research (Anderson, Benjamin, & Bartholow, 1998) indicates that the presence of guns increases the accessibility of aggressive thoughts via automatic priming. Our research examined whether this “weapons priming effect” differs depending on the structure of an individual's knowledge about guns, and if so, whether that difference results in corresponding differences in aggressive behavior. Experiment 1 revealed that individuals with prior gun experience (hunters) have more detailed and specific information about guns than do individuals with no direct gun experience (nonhunters), and that hunting experience interacts with gun type (hunting versus assault) in predicting affective and cognitive reactions to guns. Experiment 2 revealed that pictures of hunting guns were more likely to prime aggressive thoughts among nonhunters, whereas pictures of assault guns were more likely to prime aggressive thoughts among hunters. Experiment 3 showed differences in aggressive behavior following gun primes that correspond to differences in affective and cognitive responses to gun cues. Our findings are discussed in light of the General Aggression Model.     

Toward a situational analysis of gender differences in aggression

The present study explored the notion that frustration in situations congruent with traditional sex roles will elicit higher levels of aggression from both women and men than will frustration in sex-role incongruent situations. In a 2×2 design, female and male undergraduates read a feminine or masculine vignette describing an individual prevented by a classmate from practicing for an examination in dance or body-building exercises. Subjects in gender-congruent conditions perceived the examination as more important and advocated more aggressive responses than did subjects in gender-incongruent conditions. Males were significantly more aggressive than females only in the masculine situation; in the feminine situation, this difference was reduced or eliminated. The implications of these results for the interpretation of apparent sex differences in aggression are discussed.The present research was supported by Canada Council Grant S76-0344 to the second author and was conducted while the first author was supported by an Ontario Graduate Scholarship.

Effects of experimental context, demand characteristics, and situational cues: new data

When in 1964 stress induced by Restricted Environmental Stimulation (REST) was publicized, Orne and Scheibe showed "sensory deprivation" effects could be produced merely by manipulating contextual cues. Since REST is now widely regarded as beneficial, it seemed appropriate to reexamine these early findings. Stringently replicating Orne and Scheibe's procedures, 10 subjects were exposed to conditions designed to generate expected REST effects. Conditions for 10 controls suggested that nothing was expected to happen. Analyses did not confirm earlier findings as no significant difference was found between experimental and control groups on any measure. A postexperimental inquiry identified positive attitudes toward REST. The specific experimental context, demand characteristics, and situational cues did not elicit responses inconsistent with the general sociopsychological context. Researchers are cautioned about attributing causality to contextual cues because context exists merely at a correlative level with data collection.     

Controlling reactive aggression through cognitive evaluation of proactive aggression cues

The authors investigated how the relationship between the acts of proactive and reactive aggression was moderated by the individual differences in cognitive regulation of emotion. An aggression paradigm, a electrocardiogram recording, a cognitive assessment battery, and a short form IQ test were completed by 109 children, aged 8 to 13 years (Juujärvi, Kaartinen, Laitinen, Vanninen, & Pulkkinen, 2006 Juujärvi, P., Kaartinen, J., Laitinen, T., Vanninen, E. and Pulkkinen, L. 2006. Effects of physical provocations on heart rate reactivity, and reactive aggression in children. Aggressive Behavior, 32: 99–109. [Crossref], [Web of Science ®] , [Google Scholar]; Juujärvi, Kooistra, Kaartinen, & Pulkkinen, 2001 Juujärvi, P., Kooistra, L., Kaartinen, J. and Pulkkinen, L. 2001. An aggression machine: V. Determinants of reactive aggression revisited. Aggressive Behavior, 27: 430–445. [Crossref], [Web of Science ®] , [Google Scholar]; Lehto, Juujärvi, Kooistra, & Pulkkinen, 2003 Lehto, J. E., Juujärvi, P., Kooistra, L. and Pulkkinen, L. 2003. Dimensions of executive functioning: Evidence from children. British Journal of Developmental Psychology, 21: 59–80. [Crossref], [Web of Science ®] , [Google Scholar]). The less the children subdued the intensity of their defence to the attacks in the aggression paradigm, the poorer they performed in the cognitive assessment battery tasks measuring Working memory capacity and in the task assessing crystallised intelligence. The mean cardiovascular reactivity during the aggression paradigm was neither associated with the performances in either the cognitive assessment battery nor the intelligence tasks. Both information processing and knowledge dimensions of cognition contributed to regulation of emotion, but the respective effects of the processes cannot be inferred from the mean cardiovascular reactivity.     

Admission of suspicion as a function of information source: Tip-off vs. situational cues

Two studies were run in which subjects received information about a fake opponent in a two-person game either from a confederate tip off or from situational cues designed to allow the subject to penetrate the deception unaided. In both experiments, subjects given the tip off reported less suspicion of the opponent than did those using situational cues. Probes were run to check tip-off information transmission in both experiments. In Experiment II a preinstruction manipulation was used to check for awareness of the actual purpose of the experiment and suspicion of the confederate tip off, but no evidence for these unwanted artifacts was found. The results suggest that subjects may be candid about their interpretations, at least if their suspicions do not derive from peers.     

The dynamic appraisal of situational aggression: an instrument to assess risk for imminent aggression in psychiatric inpatients

Considerable research has attempted to delineate the demographic and clinical characteristics of high-risk psychiatric patients and identify salient modifiable aspects of aggression prone environments. Recently, there has also been increased interest in the development and testing of structured schemes for the assessment of risk for aggression within inpatient psychiatric settings. Although some of these methods show acceptable predictive validity, their ability to inform day-to-day treatment and management decisions is limited. The current research was designed to identify existing and novel risk factors that would assist staff to identify and manage the risk for aggression in psychiatric inpatient populations. Results showed that assessments supported by structured risk measures were more accurate than unaided clinical judgements based only on nurses' clinical experience and knowledge of the patient alone. Seven test items emerged that were maximally effective at identifying acute psychiatric patients at risk for engaging in inpatient violence within 24 hours; these items have been combined in the development of the Dynamic Appraisal of Situational Aggression. Empirical analyses and clinical experience support the efficacy of the instrument in assisting clinical staff in the identification and management of inpatient aggression.     

A meta-analysis of aggression in the presence of violent cues: Effects of gender differences and aversive provocation

Meta-analytically examines experimental studies that include violent cues in the setting and assesses the effects of aversive provocation on gender differences in aggression. The results show that when violent cues are present, men are more aggressive than women under neutral unprovoked conditions. However, when they are exposed to both violent cues and aversive provocation, men and women are equally aggressive. Differences in individual reactivity to violent cues as well as the type of aggressive response and the sex of the target also affected the magnitude of gender differences in the presence of violent cues.

Committing to implementation intentions: Attention and memory effects for selected situational cues

Two studies tested whether forming implementation intentions (Gollwitzer, Am Psychol 54:493?C503 in 1999) results in a heightened activation of specified situational cues. Going beyond prior studies, participants of the present studies specified these opportunities on their own (i.e., the action cues were not assigned by the experimenter), and activation level was assessed by attraction of attention and recall performance rather than lexical decisions. In Study 1, situational cues associated with the where and when to act on an everyday life goal attracted more attention than non-specified cues when presented to the non-attended channel in a dichotic listening task. In Study 2, the recall of specified cues was better than that of non-specified cues both 15?min after forming implementation intentions and after a delay of 2?days. Importantly, goal commitment and implementation intention commitment moderated this effect.     

Impressions of Milgram's obedient teachers: situational cues inform inferences about motives and traits

The research investigated impressions formed of a "teacher" who obeyed an experimenter by delivering painful electric shocks to an innocent person (S. Milgram, 1963, 1974). Three findings emerged across different methodologies and different levels of experimenter-induced coercion. First, contrary to conventional wisdom, perceivers both recognized and appreciated situational forces, such as the experimenter's orders that prompted the aggression. Second, perceivers' explanations of the teacher's behavior focused on the motive of obedience (i.e., wanting to appease the experimenter) rather than on hurtful (or evil) motivation. Despite this overall pattern, perceptions of hurtful versus helpful motivation varied as a function of information regarding the level of coercion applied by the experimenter. Finally, theoretically important relationships were revealed among perceptions of situations, motives, and traits. In particular, situational cues (such as aspects of the experimenter's behavior) signaled the nature of the teacher's motives, which in turn informed inferences of the teacher's traits. Overall, the findings pose problems for the lay dispositionism perspective but fit well with multiple inference models of dispositional inference.     

Gender differences in aggression: The role of displaying facial emotional cues in a competitive situation

Prior studies have shown that facial emotion displays communicate emotional states and interpersonal intentions. This study addressed gender differences in aggression based on the facial emotional cues expressed from a fictional opponent. A modified version of the competitive reaction time task (CRTT) was used to measure aggression. Participants (N = 251), between 18 and 35 years of age, were randomly assigned to one of the four conditions of the fictional opponents’ facial emotional cue displayed during the CRTT: anger, sadness, neutral, or the absence of facial expression. After each trial, participants were asked to report their own feelings and to choose a level of noise to administer to their opponent. Finally, motives for aggression were assessed. Results showed that women were less aggressive than men when receiving emotional cues of sadness and anger from the sender. In contrast, no gender differences occurred when a neutral expression was displayed or in the absence of any expression. In addition, men displayed similar levels of aggression across the four conditions, whereas women were more aggressive in both neutral and no feedback conditions than in the sad and anger conditions. Instrumental motives contributed to explaining the overall gender differences in aggression. These results suggest important moderator and mediator factors of gender differences in aggressive behavior.     

Displaced aggression is alive and well: a meta-analytic review

Content analysis of 122 social psychology textbooks confirmed that displaced aggression received a surge of attention immediately following J. Dollard, L. W. Doob, N. E. Miller, O. H. Mowrer, and R. R. Sears (1939), but subsequent interest sharply declined. Contemporary texts give it little attention. By contrast, meta-analysis of the experimental literature confirms that it is a robust effect (mean effect size = +0.54). Additionally, moderator analyses showed that: (a) The more negative the setting in which the participant and target interacted, the greater the magnitude of displaced aggression; (b) in accord with N. E. Miller's (1948) stimulus generalization principle, the more similar the provocateur and target, the more displaced aggression; and (c) consistent with the contrast effect (L. Berkowitz & D. A. Knurek, 1969), the intensity of initial provocation is inversely related to the magnitude of displaced aggression.
