Did the instigator intend to provoke? A key moderator in the relation between trait aggression and aggressive behavior

The purpose of this study was to investigate the cross‐situational consistency of trait aggression in provoking situations where an instigator (1) clearly intended to provoke, (2) clearly intended not to provoke, or (3) where presence of intention was ambiguous. It was hypothesized that cross‐situational consistency would be substantial, and that trait aggression would have the greatest impact on aggressive behavior in ambiguous situations. Participants were 80 female and 38 male undergraduate students. They completed the Aggression Questionnaire [Buss and Perry, J Pers Soc Psychol, 1992, pp. 452], read a set of 24 vignettes depicting conflict situations and rated their perceived likelihood of becoming angry and aggressive in those situations. An overall cross‐situational consistency correlation coefficient of r=.47 was found. It was also found that trait aggression had a significantly greater effect on the likelihood of aggressive responses in the ambiguous and intentional situations than it did in the unintentional situations. These results are discussed in relation to trait activation and hostile attribution bias. Aggr. Behav. 30:409–424, 2004. © 2004 Wiley‐Liss, Inc.     

道德推脱对员工道德决策的影响：德行领导的调节作用

运用问卷调查的方法,以819名员工为研究被试,探讨了德行领导在道德推脱影响道德决策过程中的调节作用。采用层次回归分析的方法研究发现：德行领导对道德推脱与道德识别、道德判断之间的关系具有调节作用;但德行领导不会对道德推脱与道德意图之间的关系产生调节作用,而会对道德意图产生显著的直接影响。     

A Communicative Conception of Moral Appraisal

I argue that our acts of moral appraisal should be communicative. Praise and blame should communicate, to the appraised, information about their status and competences as moral agents; that they are recognised by the appraiser as a competent moral agent, and thus a legitimate candidate for appraisal. I argue for this thesis by drawing on empirical data about factors that can affect motivation. On the basis of such data, I formulate a constraint, and argue that two prominent models of moral appraisal – a consequentialist model and Wallace’s ‘evaluative response’ model – violate this constraint. The model that I propose – the communicative conception of appraisal – does not violate this constraint. This conception, I argue, can provide a fuller picture of the role of appraisals in deepening agents’ commitment to moral norms. On this model, praise and blame has not only an evaluative component, but also communicates to the agent competence affirming information.

Communicative Context Affects Use of Referential Prosody

The current study assessed the extent to which the use of referential prosody varies with communicative demand. Speaker–listener dyads completed a referential communication task during which speakers attempted to indicate one of two color swatches (one bright, one dark) to listeners. Speakers' bright sentences were reliably higher pitched than dark sentences for ambiguous (e.g., bright red versus dark red) but not unambiguous (e.g., bright red versus dark purple) trials, suggesting that speakers produced meaningful acoustic cues to brightness when the accompanying linguistic content was underspecified (e.g., “Can you get the red one?”). Listening partners reliably chose the correct corresponding swatch for ambiguous trials when lexical information was insufficient to identify the target, suggesting that listeners recruited prosody to resolve lexical ambiguity. Prosody can thus be conceptualized as a type of vocal gesture that can be recruited to resolve referential ambiguity when there is communicative demand to do so.     

Aggression inhibition in high‐ and low‐risk subjects for child physical abuse: effects of a child's hostile intent and the presence of mitigating information

Exposure of an aggressor to the suffering of his/her victim generally inhibits subsequent attacks [e.g. Baron, 1971a] presumably because of an empathic process. Physically abusive parents and individuals at high risk for child physical abuse are thought to present a deficit in empathy [e.g. Milner, Halsey and Fultz, 1995]. The present research was designed to investigate whether high‐risk, compared to low‐risk, subjects for child physical abuse select more aggressive responses and aggress with more intensity toward a supposed child whose behavior is adequate, inadequate or ambiguous in the presence of the child's pain cues. A second objective was to explore whether high‐risk, compared to low‐risk, subjects for child physical abuse fail to adequately integrate mitigating information and, therefore, do not inhibit their aggressive behavior following the receipt of mitigating information before or during an inadequate child behavior. Participants were engaged in an experimental task that involved attempting to teach a child how to proceed accurately through a computer‐displayed maze and were given the opportunity to send positive (pleasant sounds and happy faces) and negative feedback (mad faces and unpleasant sounds) to the child. Two hundred and fifty undergraduate students participated in the experiment. A 2 × 5 factorial design based on two levels of the participant's risk status (high, low) and five conditions based on the child's behavior and the introduction of mitigating information was employed. As expected, low‐risk, compared to high‐risk, subjects showed less aggression when mitigating information was provided. Aggr. Behav. 32:1–15, 2006. © 2006 Wiley‐Liss, Inc.     

Conceptual Similarity and Communicative Need Shape Colexification: An Experimental Study

Colexification refers to the phenomenon of multiple meanings sharing one word in a language. Cross-linguistic lexification patterns have been shown to be largely predictable, as similar concepts are often colexified. We test a recent claim that, beyond this general tendency, communicative needs play an important role in shaping colexification patterns. We approach this question by means of a series of human experiments, using an artificial language communication game paradigm. Our results across four experiments match the previous cross-linguistic findings: all other things being equal, speakers do prefer to colexify similar concepts. However, we also find evidence supporting the communicative need hypothesis: when faced with a frequent need to distinguish similar pairs of meanings, speakadjust their colexification preferences to maintain communicative efficiency and avoid colexifying those similar meanings which need to be distinguished in communication. This research provides further evidence to support the argument that languages are shaped by the needs and preferences of their speakers.     

The perception of available social support is related to reduced cardiovascular reactivity in phase II cardiac rehabilitation patients

Objective  Numerous studies have observed a relationship between social support (SS) and post coronary event survival. Laboratory research suggests one mechanism regulating this relationship may be exaggerated cardiovascular reactivity (CVR). What has not been as well explored is (1) whether the SS-CVR relationship holds up for a heart diseased sample, and (2) whether this relationship is evidenced only in supportive environments or can be found as a function of generalized perception of being socially supported. Thus, the purpose of this study was to examine the relationship of perceived SS and a locally supportive presence to CVR to a speech-induced stressor in post coronary event patients. Method  Forty-one Phase II cardiac rehabilitation patients participated in a research protocol that consisted of BP and HR measurement during two identical affective stress interviews where local support was systematically varied by presence or absence of a friendly small pet dog. Perception of SS was assessed by completion of psychosocial questionnaire packet that included measures of SS, anger expression and pet attachment. Results  Repeated measures ANCOVAs revealed that patients who believed they had greater SS available to them during difficult times exhibited significantly less CVR for MAP (p<.007) and DBP (p<.024). No significant main effects for local support (pet presence) and no interactions between local and perceived support were found. Conclusions  These findings are of interest as they: (a) demonstrate an association between reduced CVR and higher (amounts of) SS in a clinical sample; (b) demonstrate this effect in a sample medicated to dampen CV levels and surges; (c) suggest that perceived amount of SS provides an ameliorative influence on CVR independent of situational support; (d) suggest that for certain conditions pet-models of support may be ineffective at establishing an local support presence.     

Hemispheric alpha asymmetries of words with positive, negative, and neutral arousal values preceding tasks of recall and recognition: Electrophysiological and behavioral results from stuttering males and nonstuttering males and females

Hemispheric alpha asymmetries were obtained for stuttering males and nonstuttering males and females for words of positive, negative, and neutral arousal values. Electroencephalographic data were gathered during the presentations of stimulus words and during the actual nonoral recall and recognition of the stimulus items. Stuttering males demonstrated right-hemispheric alpha suppression across stimulus words and tasks as contrasted with left-hemispheric alpha suppression for the nonstuttering males and females. Stuttering males were also shown to recall and recognize fewer words than the nonstuttering subjects across arousal categories. Subjects were also administered a modified version of A. Paivio's (1971, In B. Randhawa & W. Coffman, Eds., Visual thinking, learning, and communication, New York: Academic Press) Individual Differences Questionnaire (IDQ). Results showed our stuttering males to have obtained lower scores on the verbal and imagery questions of the IDQ as compared to the nonstuttering groups. Hemispheric alpha asymmetry results and memory performance from the stuttering males are discussed relative to nonsegmental, right-hemispheric processing strategies.     

Demographic characteristics and treatment experiences of women and men who stutter

This paper reports interview data collected from ten men and ten women who stutter. The responses of the subjects tend to (a) highlight the multidimensionality of stuttering, (b) provide additional support for the conclusion drawn earlier of gender differences in stuttering symptomatology, and (c) raise questions about the manner in which stuttering is treated.
