Inferring the size of a goal object from an actor's grasping movement in 6‐ and 9‐month‐old infants

The present study applied a preferential looking paradigm to test whether 6‐ and 9‐month old infants are able to infer the size of a goal object from an actor's grasping movement. The target object was a cup with the handle rotated either towards or away from the actor. In two experiments, infants saw the video of an actor's grasping movement towards an occluded target object. The aperture size of the actor's hand was varied as between‐subjects factor. Subsequently, two final states of the grasping movement were presented simultaneously with the occluder being removed. In Experiment 1, the expected final state showed the actor's hand holding a cup in a way that would be expected after the performed grasping movement. In the unexpected final state, the actor's hand held the cup at the side which would be unexpected after the performed grasping movement. Results show that 6‐ as well as 9‐month‐olds looked longer at the unexpected than at the expected final state. Experiment 2 excluded an alternative explanation of these findings, namely that the discrimination of the final states was due to geometrical familiarity or novelty of the final states. These findings provide evidence that infants are able to infer the size of a goal object from the aperture size of the actor's hand during the grasp.     

Some Outcomes of Pressure,Ingratiation, and Rational Persuasion Used With Peers in the Workplace1

In a cross‐sectional organizational field study, the effects of ingratiation, pressure, and rational persuasion on performance appraisal, compliance gaining, and reactance were investigated. Actors were asked to describe their lateral‐influence strategies, and peers were asked to assess actors’ impact. Actors and assessors from 140 German lateral‐influence dyads who were public officeholders and employees participated in the study. The data support the hypothesis that the more an actor uses rational persuasion and the longer the assessor has known the actor, the more positively the assessor will evaluate the actor's task performance. In addition, the results support the hypothesis that the more an actor uses ingratiation and the longer the assessor has known the actor, the more positively the assessor will evaluate actor's compliance‐gaining success.     

Long‐term partners' relationship satisfaction and their perceptions of each other's attachment insecurities

In this research, we examined actors' and partners' perceptions of each other's attachment insecurities and the associations of these perceptions with relationship satisfaction. A sample of 148 heterosexual couples completed measures of self and partner attachment insecurities and relationship satisfaction. Results indicate that partners agree in their perceptions of their own and each other's attachment insecurities (anxiety and avoidance). Based on the actor–partner interdependence model (APIM), we also found that both actors' scores on avoidance and their perceptions of their partner's degree of avoidanc are associated with lower relationship satisfaction. Finally, we found that the way an actor perceives his or her partner's avoidance plays a mediational role in the association between partner's self‐reported avoidance and actor's relationship satisfaction.     

The role of social perspective in perceiving the causes of success and failure1

An experiment was conducted to test the hypothesis that observers' causal attributions about an actor's performance at a task would be affected by their social perspective in observing the situation. Observer subjects were either assigned to serve in a role comparable to that of observer-subjects in most actor-observer experiments or were assigned a distinctive role more divergent from the social perspective of the actor. As expected, observers with a similar social perspective to that of the actor made more flattering attributions about the actor's performance than observers with a dissimilar social perspective. We concluded that actor-observer differences in attribution for an actor's performance in any one experiment cannot be taken as definitive evidence either for or against the defensive attribution idea.     

Looking at the actor's face: Identity cues and attentional focus in false memories of action performance from observation

Observing another's actions can induce false memories of self-performance. We investigated whether such observation inflation depends on the discriminability between the self and the observed actor. Discriminability was manipulated by presenting actions either with or without a key visual identity cue, i.e., the actor's face. We also examined whether self–other confusions in the face-visible condition depend on attentional focus (directed to the observed action vs. the actor's face). In the action-only condition, observation inflation was significant and greater than in the face-visible conditions, in which the effect was moderated by attentional focus: It persisted under an action focus but was eliminated under a face focus. Findings for correct memories of self-performance suggest that the reduced effect is not merely due to weaker encoding of the actions themselves. We conclude that self–other confusions in action memory are constrained by the availability of distinctive non-self cues during observation, and sustained by a visual focus on observed actions.     

Observation of another's action but not eye gaze triggers allocentric visual perspective

In the present paper, we investigated whether observation of bodily cues—that is, hand action and eye gaze—can modulate the onlooker's visual perspective taking. Participants were presented with scenes of an actor gazing at an object (or straight ahead) and grasping an object (or not) in a 2?×?2 factorial design and a control condition with no actor in the scene. In Experiment 1, two groups of subjects were explicitly required to judge the left/right location of the target from their own (egocentric group) or the actor's (allocentric group) point of view, whereas in Experiment 2 participants did not receive any instruction on the point of view to assume. In both experiments, allocentric coding (i.e., the actor's point of view) was triggered when the actor grasped the target, but not when he gazed towards it, or when he adopted a neutral posture. In Experiment 3, we demonstrate that the actor's gaze but not action affected participants' attention orienting. The different effects of others' grasping and eye gaze on observers' behaviour demonstrated that specific bodily cues convey distinctive information about other people's intentions.     

Infants’ developing understanding of the link between looker and object

Three studies investigated infants’ understanding that gaze involves a relation between a person and the object of his or her gaze. Infants were habituated to an event in which an actor turned and looked at one of two toys. Then, infants saw test events in which (1) the actor turned to the same side as during habituation to look at a different toy, or (2) the actor turned to the other side to look at the same toy as during habituation. The first of these involved a change in the relation between actor and object. The second involved a new physical motion on the part of the actor but no change in the relation between actor and object. Seven‐ and 9‐month‐old infants did not respond to the change in relation between actor and object, although infants at both ages followed the actor's gaze to the toys. In contrast, 12‐month‐old infants responded to the change in the actor–object relation. Control conditions verified that the paradigm was a sensitive index of the younger infants’ representations of action: 7‐ and 9‐month‐olds responded to a change in the actor–object relation when the actor's gaze was accompanied by a grasp. Taken together, these findings indicate that gaze‐following does not initially go hand in hand with understanding the relation between a person who looks and the object of his or her gaze, and that infants begin to understand this relation between 9 and 12 months.     

Psychological Correlates of Perception of Sexual Intent in Women

Abstract

In a sample of 183 men and 186 women, the authors assessed (a) the relative contributions of gender and level of nonverbal social cues to the perception of a female actor's sexual intent during a videotaped social interaction with a man and (b) the association between those variables and personality traits implicated in faulty sexual-information processing. The authors assessed those variables while the participants viewed 1 of 3 film segments depicting a female-male interaction. The authors experimentally manipulated eye contact, touch, physical proximity, and female clothing. At all levels of those nonverbal cues, the men perceived more sexual intent in the female actor than did the women. The perception of the female actor's sexual intent increased as the nonverbal cues in the film segments were magnified: Both actors displayed more eye contact, touch, and physical proximity, and the female actor wore more revealing clothing. Relative to the women, the men demonstrated greater sexual preoccupation and reduced sociosexual effectiveness, variables associated with inferring greater sexual intent in the female actor.     

Perspective Effects on Causal Attributions of Success and Failure

The performance attributions of actors (participants on a task or in an interaction), active observers (co-actors who make observations of the actor) and passive observers (non-participants who observe but do not interact with the actor) were compared on a task in which actors succeeded or failed after competing or working independently. Contrary to Jones and Nisbett's (1971) divergent perspectives hypothesis, the results indicated that the subjects' person attributions were influenced interactively by the actor's outcome and the subjects' perspective while their situation attributions were influenced interactively by their perspective and the nature of the task. The implications of these findings for the divergent perspectives hypothesis were discussed.     

Identification, situational constraint, and social cognition: studies in the attribution of moral responsibility

In three experiments we studied lay observers' attributions of responsibility for an antisocial act (homicide). We systematically varied both the degree to which the action was coerced by external circumstances and the degree to which the actor endorsed and accepted ownership of the act, a psychological state that philosophers have termed "identification." Our findings with respect to identification were highly consistent. The more an actor was identified with an action, the more likely observers were to assign responsibility to the actor, even when the action was performed under constraints so powerful that no other behavioral option was available. Our findings indicate that social cognition involving assignment of responsibility for an action is a more complex process than previous research has indicated. It would appear that laypersons' judgments of moral responsibility may, in some circumstances, accord with philosophical views in which freedom and determinism are regarded to be compatible.     

Effects of Job Conditions on Worker Perceptions: Ambient Stimuli vs. Group Influence1

This study identifies the direct effects of objective job conditions on individual perceptions of job conditions. The assumptions that (1) group perceptions mediate the relationship between objective job conditions and individual perceptions of job conditions, and (2) group consensus enhances the relationship be-between group perceptions and individual perceptions were tested. Respondents were white, male, blue collar workers (N= 1240) in a tire and rubber manufacturing plant. Work groups (N= 156), consisting of four or more men on the same shift, in the same department, and who had the same supervisor, were identified. Objective job conditions included work group size, pay style, shift, and job technology. Group and individual perceptions of amount of work-load, role conflict, responsibility pressure, and intrinsic rewards were measured. The findings indicated that objective job conditions have important effects on individual perceptions of stressful and rewarding job conditions. Smaller work groups, and jobs that pay on an hourly rather than a piece-work basis, allow for some control over the pace of work, and allow for interaction among fellow workers resulted in higher levels of intrinsic rewards and lower levels of workload, role conflict, and responsibility pressures. An intriguing pattern appeared where, in perceptions involving interpersonal relations, work group influence was relatively more important than objective job conditions. When assessing task oriented aspects of work, objective job conditions were more important than group perceptions.     

Blameworthiness,desert, and luck

Philosophers disagree about whether outcome luck can affect an agent's “moral responsibility.” Focusing on responsibility's “negative side,” some maintain, and others deny, that an action's results bear constitutively on how “blameworthy” the actor is, and on how much blame or punishment they “deserve.” Crucially, both sides to the debate assume that an actor's blameworthiness and negative desert are equally affected—or unaffected—by an action's results. This article challenges that previously overlooked assumption, arguing that blameworthiness and desert are distinct moral notions that serve distinct normative functions: blameworthiness serves a liability function (removing a bar to otherwise impermissible treatments), whereas desert serves a favoring function (contributing new value to states of affairs, or providing new reasons for responsive treatments). Having distinguished (negative) desert from blameworthiness, the article proposes a novel resolution to the outcome-luck debate: that results do not affect an agent's liability to blame, but do affect the amount and severity of blame to which the agent is justly liable, including by affecting the severity of blame that the agent deserves.     

Adrenalectomy Causes Oxidative Damage and Monoamine Increase in the Brain of Rats and Enhances Immobilization Stress-Induced Oxidative Damage and Neurotransmitter Changes

The paradox that increased levels of glucocorticoids can either enhance or suppress the organism's defense against stress, has been an obstacle to formulating a unified picture of glucocorticoid function. To clarify the glucocorticoid paradox, we examined male Sprague-Dawley rats exposed to immobilization stress and/or bilateral adrenalectomy (ADX), and measured oxidative damage to lipid, protein, and DNA, as well as monoamine neurotransmitter turnover. ADX, which is similar to stress, induces an increase in lipid peroxidation and protein oxidation, accompanied by increased monoamine neurotransmitter turnover in several regions of the brain of rats. The effect of ADX is greater than that induced by short-term immobilization stress. In addition, ADX enhances stress-induced oxidative damage and increase of monoamine neurotransmitter turnover. These results, together with our previous finding that long-term stress causes oxidative damage to the brain, suggest that stress levels of glucocorticoids, or levels lower than basal, cause oxidative damage. However, basal levels of glucocorticoids appear to buffer against oxidative damage. These findings provide possible mechanisms to understand the glucocorticoid paradox, and support the stress-oxidative hypothesis of aging acceleration.     

Behavioral Causality Orientations and Investment Decisions Following Negative Feedback

Individual differences in the locus of causality for behavior are seldom considered in tests of regulatory events (e. g., feedback and coercion). This study examined the relationship between Deci and Ryan's (1985a) causality orientation constructs and decision makers' behavioral intention responses to negative feedback following an initial decision. A laboratory experiment involved 98 Singaporean business students in a commitment escalation context in which sunk costs for an initial investment failure could be recovered by reinvesting in that prospect in preference to selecting an alternative that had previously performed better. Consistent with various theories of the escalation effect, in which subjects responsible for prior negative outcomes tend to reinvest in the initially chosen project, control orientation was positively associated with reinvestment and impersonal orientation was negatively related to reinvestment. The influence of personality on reinvestment/withdrawal behavior was moderated by the experimental condition of responsibility for the initial sunk cost. We discuss the implications of these findings for the construct validity of the causality orientations, the role of personality in commitment escalation, and the important role that individual differences in perceptions of regulatory events may play in determining behavior.     

Citizens' Sense of Justice and the Legal System

When an actor commits a wrong action, citizens have perceptions of the kind of responsibility the actor incurs, the degree to which the act was mitigated or justified, and the appropriate punishment for the actor. The legislatively mandated law of criminal courts, statutes, and criminal codes deals with the same issues. Experimental evidence shows that there are important discrepancies between the principles that people and legal codes use to assign responsibility. That is, the moral retributive-justice principles that people use are sometimes in conflict with the directions in which modern code drafters are taking criminal law. These discrepancies may cause citizens to feel alienated from authority, and to reduce their voluntary compliance with legal codes.     

Selecting explanations from causal chains: Do statistical principles explain preferences for voluntary causes?

We investigate whether people prefer voluntary causes to physical causes in unfolding causal chains and whether statistical (covariation, sufficiency) principles can predict how people select explanations. Experiment 1 shows that while people tend to prefer a proximal (more recent) cause in chains of unfolding physical events, causality is traced through the proximal cause to an underlying distal (less recent) cause when that cause is a human action. Experiment 2 shows that causal preference is more strongly correlated with judgements of sufficiency and conditionalised sufficiency than with covariation or conditionalised covariation. In addition, sufficiency judgements are partial mediators of the effect of type of distal cause (voluntary or physical) on causal preference. The preference for voluntary causes to physical causes corroborates findings from social psychology, cognitive neuroscience and jurisprudence that emphasise the primacy of intentions in causal attribution processes.

Effect of counterfactual and factual thinking on causal judgements

The significance of counterfactual thinking in the causal judgement process has been emphasized for nearly two decades, yet no previous research has directly compared the relative effect of thinking counterfactually versus factually on causal judgement. Three experiments examined this comparison by manipulating the task frame used to focus participants' thinking about a target event. Prior to making judgements about causality, preventability, blame, and control, participants were directed to think about a target actor either in counterfactual terms (what the actor could have done to change the outcome) or in factual terms (what the actor had done that led to the outcome). In each experiment, the effect of counterfactual thinking did not differ reliably from the effect of factual thinking on causal judgement. Implications for research on causal judgement and mental representation are discussed.
