Perceived causality and perceived force: Same or different?

Visually perceived interactions between objects, such as animated versions of billiard ball collisions, give rise to causal impressions, impressions that one object produces some effect in another, and force impressions, impressions that one object exerts a certain amount of force on another. In four experiments, evidence for strong divergence between these two impressions is reported. Manipulations of relative direction of motion and point of contact between the objects had different effects on the causal and force impressions (Experiment 1); delay between one object contacting another and the latter starting to move had a stronger effect on the causal impression than on the force impression (Experiment 2); a context of other moving objects significantly weakened the causal impression but not the force impression (Experiment 3); and there was an inverse relation between an impression of one object penetrating another and the amount of force the former was perceived as exerting on the latter (Experiment 4). These findings are explained in terms of differential effects of instructions on attention, and also in terms of differences in meaning between force and causality.     

First Impressions of the Face: Predicting Success

The human tendency to form impressions of others is ubiquitous and consequential. Consensus, or agreement among individuals, regarding their first impressions based on the facial appearance of others can lead to the treatment of other individuals in particular ways that shape their outcomes and behaviors. For an impression to be considered accurate it must not only be consensual but must also show correspondence to an external criterion, such as whether impressions of individuals’ leadership ability are related to the performance of their group or organization. Many of our first impressions may not have valid external criteria to enable an assessment of the accuracy of the impression. Yet, whether our impressions are accurate or merely consensual, they can still often predict important outcomes. A limited but growing literature has shown that our impressions can be both consensual and predictive despite important social and perceptual distinctions, such as differences in culture.     

Group impressions as dynamic configurations: the tensor product model of group impression formation and change

Group impressions are dynamic configurations. The tensor product model (TPM), a connectionist model of memory and learning, is used to describe the process of group impression formation and change, emphasizing the structured and contextualized nature of group impressions and the dynamic evolution of group impressions over time. TPM is first shown to be consistent with algebraic models of social judgment (the weighted averaging model; N. Anderson, 1981) and exemplar-based social category learning (the context model; E. R. Smith & M. A. Zárate, 1992), providing a theoretical reduction of the algebraic models to the present connectionist framework. TPM is then shown to describe a common process that underlies both formation and change of group impressions despite the often-made assumption that they constitute different psychological processes. In particular, various time-dependent properties of both group impression formation (e.g., time variability, response dependency, and order effects in impression judgments) and change (e.g., stereotype change and group accentuation) are explained, demonstrating a hidden unity beneath the diverse array of empirical findings. Implications of the model for conceptualizing stereotype formation and change are discussed.     

Keeping up impressions: Inferential rules for impression change across the Big Five

Not all first impressions have equal longevity. Which kinds of impression have the greatest mobility—downward and upward—over the course of acquaintanceships? In this article, we propose an inferential account of impression maintenance across Big Five trait domains. With data from field and laboratory studies, we provide evidence that positive impressions of agreeableness (A), conscientiousness (C), and emotional stability (ES) are especially vulnerable to small amounts of contrary evidence, whereas positive first impressions of extraversion (E) and openness (O) are more resistant to contrary information. Impressions of E and O demonstrated minimal susceptibility to negativity effects in a longitudinal study of college roommate impressions (Study 1), in a study of perceivers’ implicit theories about different trait domains (Study 2), and in an experimental study of manipulated impression change (Study 3).     

Redefining the psychological autopsy: A proposal for collaboration between forensic pathology and investigative psychology

Excepting psychiatry, psychology and medicine remain largely separate disciplines. In forensic inquiries, the psychologist assesses the mind, whereas the pathologist examines the body. Both fields, however, actively participate in the same investigations, albeit from different standpoints, contributing to explorations of crime scene dynamics, identification of offenders, and legal proceedings. In recent years, peer review has become a staple of research, because subjecting work to scrutiny by other experts promotes accuracy. Forensic pathologists would benefit from insights provided by investigative psychology, particularly if asked to apply psychology to their testimony, and integration with forensic pathology may increase the acceptance of empirical profiling evidence in the courtroom. Additionally, incorporation of medical findings—such as wound patterns, evidence of range of fire, and cause of death determinations—could add another level of detail to techniques like smallest space analysis. The following functions as a proposal for the incorporation of forensic pathological findings into investigative psychology research and the application of investigative psychology to forensic pathology practice. Cooperation has the potential to extend the scope of knowledge in both disciplines, to increase their applicability to and acceptance in legal contexts and to maximize the probative value of evidence provided in the court of law.     

Prime diagnosticity in short-term repetition priming: is primed evidence discounted, even when it reliably indicates the correct answer?

The authors conducted 4 repetition priming experiments that manipulated prime duration and prime diagnosticity in a visual forced-choice perceptual identification task. The strength and direction of prime diagnosticity produced marked effects on identification accuracy, but those effects were resistant to subsequent changes of diagnosticity. Participants learned to associate different diagnosticities with primes of different durations but not with primes presented in different colors. Regardless of prime diagnosticity, preference for a primed alternative covaried negatively with prime duration, suggesting that even for diagnostic primes, evidence discounting remains an important factor. A computational model, with the assumption that adaptation to the statistics of the experiment modulates the level of evidence discounting, accounted for these results.     

Cluster Analysis Examination of Serial Killer Profiling Categories: A Bottom‐Up Approach

Two studies explored the validity of dichotomous classification of organised/disorganised serial killers and the four typologies (visionary, mission, hedonistic, and power/control) adopted by the Federal Bureau of Investigation (FBI). Tables documenting crime scene criteria were devised consisting of 50 typifying different crime scenes (Study 1) and 48 crime scenes (taken from the 50 crime scene criteria) with a further 10 motive‐based crime scene criteria (Study 2). Adopting content analysis, crime scenes depicted for 40 (Study 1) and 40 (Study 2) serial killers using secondary sources of data were dichotomously coded for the presence or absence of the crime scene criteria. These data were inputted for agglomerative hierarchical cluster using Ward's method as the clustering algorithm. Differences in the nature of clusters were found for male and female serial killers; however, there was no empirical support for the organised/disorganised classifications or the four typologies. The ‘bottom‐up’ approach resulted in clusters from the different crime scene criteria that helped to understand how these criteria were associated within the serial killer cohort considered. It is concluded that the resulting clusters in both studies support the notion of there being an underlying organised element to most serial murder and that serial murders differ according to the nature of disorganised crime scene criteria present.

Personality Expression and Impression Formation in Online Social Networks: An Integrative Approach to Understanding the Processes of Accuracy,Impression Management and Meta‐accuracy

In this paper, we investigate personality expression and impression formation processes in online social networks (OSNs). We explore whether, when and why people accurately judge others' personalities (accuracy), successfully manage the impressions that others form of them (impression management) and accurately infer others' impressions of them (meta‐accuracy) at zero acquaintance. On the basis of targets' OSN profiles (N = 103), overall perceiver impressions were collected and compared with targets' self‐view, desired impression and meta‐perception. In addition, independent groups of thin‐slice perceivers based their personality impressions solely on one of four kinds of information within the OSN profiles (profile picture, interests field, group list and notice board), and more than 300 OSN cues (e.g. attractive person and number of friends) were coded. Results showed evidence of accuracy, impression management and meta‐accuracy, but their extent was moderated by the trait (e.g. Big Five and self‐esteem), the kind of information and the interplay of trait and information. Findings could be explained by cue expression and cue utilization processes (lens model analyses). Future prospects for studying personality impressions in online and offline environments are discussed. Copyright © 2013 European Association of Personality Psychology.     

Comparative Diagnostic Judgments from the Rorschach and the MMPI

Three experienced psychologists made diagnostic judgments from the Rorschach, the MMPI, and gave an overall diagnostic impression for 50 male and 48 female patients. Judgment on the first test viewed was given before looking at the second test. Order of viewing the tests and sex of patient were counterbalanced. The results indicated (a) the judges consistently rated the tests on a given individual as agreeing on diagnostic impression significantly more often than disagreeing; (b) interjudge agreement was low but significant for the MMPI and overall impressions, not significant for the Rorschach impressions; (c) in cases of disagreement, there was a highly significant tendency for the Rorschach to be seen as indicating more pathology than the MMPI.     

Investigating the nature of expressiveness in stranger,acquaintance and intrafamilial homicides

This study explores the role of the victim–offender relationship in the dynamics of homicide, by examining the crime scene behaviour of 25 intrafamilial, 30 acquaintance and 27 stranger homicide offenders (n = 82). Six crime scene variables were examined: ‘Weapon from the scene’, ‘Excessive wounding’, ‘Facial trauma’, ‘Multiple wounds to a single area’, ‘Post‐mortem activity’ and ‘Manual violence’. The first objective was to identify whether these variables could be combined to form a partially ordered scale of expressiveness. The second was to examine whether the nature of this expressive crime scene varied according to the victim and offender relationship. It was hypothesised that the intrafamilial homicides would be characterised by a more expressive crime scene. This was examined by Partial Order Scalogram Analysis which supported the hypothesised link between the level of expressed emotion evident in the crime scene and the nature of the victim–offender relationship. Further analysis on the individual variables revealed that the best single predictor of the relationship between victim and offender was the presence of multiple wounding. These findings are discussed both as contributing to a theoretical understanding of the emotional salience of crime scene actions when killing a family member, and in practical terms in relation to the significance of these variables for both police investigations and clinical interventions with homicide perpetrators.

Disentangling stereotype activation and stereotype application in the stereotype misperception task

When forming impressions about other people, stereotypes about the individual's social group often influence the resulting impression. At least 2 distinguishable processes underlie stereotypic impression formation: stereotype activation and stereotype application. Most previous research has used implicit measures to assess stereotype activation and explicit measures to assess stereotype application, which has several disadvantages. The authors propose a measure of stereotypic impression formation, the stereotype misperception task (SMT), together with a multinomial model that quantitatively disentangles the contributions of stereotype activation and application to responses in the SMT. The validity of the SMT and of the multinomial model was confirmed in 5 studies. The authors hope to advance research on stereotyping by providing a measurement tool that separates multiple processes underlying impression formation.     

Motion impressions enhanced by converging motion lines

We investigated how motion lines drawn in the background of a running human silhouette affect motion impressions of a runner in a static image. Observers evaluated the strength and direction of motion impression. The results show that parallel lines do not enhance frontoparallel motion impressions, while converging lines do so in an in-depth direction. This is a counter-example to the hypothesis that motion lines in the background represent motion streaks of the background when one visually tracks a moving object.     

Why most people disapprove of me: experience sampling in impression formation

Individuals are typically more likely to continue to interact with people if they have a positive impression of them. This article shows how this sequential sampling feature of impression formation can explain several biases in impression formation. The underlying mechanism is the sample bias generated when the probability of interaction depends on current impressions. Because negative experiences decrease the probability of interaction, negative initial impressions are more stable than positive impressions. Negative initial impressions, however, are more likely to change for individuals who are frequently exposed to others. As a result, systematic differences in interaction patterns, due to social similarity or proximity, will produce systematic differences in impressions. This mechanism suggests an alternative explanation of several regularities in impression formation, including a negativity bias in impressions of outgroup members, systematic differences in performance evaluations, and more positive evaluations of proximate others.     

Doing More Harm Than Good: When Is Impression Management Likely to Evoke a Negative Response?

Impression management tactics do not always successfully influence observers, and may in fact create undesirable impressions. Hypotheses are derived concerning the conditions under which observers may respond more or less positively to impression management tactics. Qualitative data from an experiment manipulating two impression management tactics—self-handicapping and causal accounts—in conjunction with successful or failed performance outcomes were content-analyzed for subjects' general impressions of an actor. In turn, these ratings were subjected to an ANOVA. Results suggest that impression management tactics are differentially effective and under certain conditions can actually create negative images. The consistency of impression management tactics, performance outcomes, and observers' expectations form the basis for observers' general impressions of impression managers.     

Impressions formed in response to public self-evaluation maintenance strategies

Two studies examined the impressions formed in response to public self-evaluation maintenance strategies. According to Tesser’s (1988) self-evaluation maintenance (SEM) model, a person who has been outperformed by a close other perceives the field of performance as less relevant to preserve self-evaluation. Tesser and Paulhus (1983) showed that this same strategy is used for the purpose of impression management, or public self-evaluation maintenance. The present research examined the SEM model variables from the view of impression formation. In the first study, information regarding field relevance and psychological closeness was conveyed by the experimenter. In this context, field relevance had a significant impact on perception of competence. In the other study, in which the information was conveyed by the target person, relevance and closeness influenced the perception of manipulativeness and sociability. The results are discussed in terms of the importance of investigating the SEM processes from the impression formation perspective.     

Similarity to the self influences cortical recruitment during impression formation

Prior work has shown that whether or not someone is similar to the self influences person memory—a type of self-reference effect for others. In this study, we were interested in understanding the neural regions supporting the generation of impressions and subsequent memory for targets who vary in similarity to the self. Participants underwent fMRI scanning while forming positive or negative impressions of face–behavior pairs. We tested participants’ memory for their generated impressions and then back-sorted the impression trials (encoding) into different levels of self-similarity (high, medium, low) using a self-similarity posttest that came after recognition. Extending prior behavioral work, our data confirmed our hypothesis that memory would be highest for self-similar others and lowest for self-dissimilar others. Dorsal anterior cingulate cortex (dACC) activity increased with self-similarity (high > medium > low) to targets, regardless of later memory for them. An analysis of regions supporting impression memory revealed a double dissociation within medial temporal lobe regions: for similar others, amygdala recruitment supported memory, whereas for dissimilar others, hippocampal activation supported memory. These results suggest that self-similarity influences evaluation and memory for targets but also affects the underlying neural resources engaged when thinking about others who vary in self-similarity.
