Facial comparison behaviour of forensic facial examiners

Facial examiners make visual comparisons of face images to establish the identities of persons in police investigations. This study utilised eye-tracking and an individual differences approach to investigate whether these experts exhibit specialist viewing behaviours during identification, by comparing facial examiners with forensic fingerprint analysts and untrained novices across three tasks. These comprised of face matching under unlimited (Experiment 1) and time-restricted viewing (Experiment 2), and with a feature-comparison protocol derived from examiner casework procedures (Experiment 3). Facial examiners exhibited individual differences in facial comparison accuracy and did not consistently outperform fingerprint analysts and novices. Their behaviour was also marked by similarities to the comparison groups in terms of how faces were viewed, as evidenced from eye movements, and how faces were perceived, based on the made feature judgements and identification decisions. These findings further understanding of how facial comparisons are performed and clarify the nature of examiner expertise.     

The relationship between personality, social functioning, and depression: a structural equation modeling analysis

The relationship between personality, social functioning, and depression remains unclear. The present study employs structural equation modeling to examine the mediating role of social functioning between harm avoidance (HA), self-directedness (SD), and depression. A sample of 902 individuals completed a self-report questionnaire consisting of the following scales: HA and SD subscales of the Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI), and Social Adaptation Self-Evaluation Scale (SASS). Structural equation modeling via analysis of moment structure was used to estimate the fit of nine related models. Results indicated that social functioning is a mediator between harm avoidance or self-directness and depression. Self-directedness was also shown to have direct effects on depression. The results support the social reinforcement theory of depression and provide a theoretical account of how the variables are related based on correlation methods. Suggestions are offered for future experimental and longitudinal research.     

Pattern discrimination in the near-ultraviolet by pigeons

Four pigeons were tested, using an operant conditioning method with successive stimulus presentation, on a pattern discrimination task to determine whether or not they could distinguish patterns that were illuminated by near-ultraviolet (UV) light. Tests at red, green, and UV wavelengths showed that they could significantly discriminate not only the chromatic stimuli that were visible to human observers but also the UV-illuminated patterns that humans could not see. In control sessions, the birds’ performance deteriorated to chance levels when these UV wavelengths were blocked by additional filters. Their discrimination of UV patterns precludes that the pigeon’s known sensitivity to UV is mediated by a preretinal fluorescence, as is probably the case in some other animals, since such a fluorescence does not permit a focused retinal image. Possible retinal mechanisms mediating their UV detection are discussed.     

Pigeons (Columba livia) learn to link numerosities with symbols

After responding to each element in varying, successive numerosity displays, pigeons (Columba livia) had to choose, out of an array of symbols, the symbol designated to correspond to the preceding number of elements. After extensive training, 5 pigeons responded with significant accuracy to the numerosities 1 to 4, and 2 pigeons to the numerosities 1 to 5. Several tests showed that feedback tones accompanying element pecks, the familiarity of element configurations, and the shape of the elements were not crucial to this performance. One test, however, indicated that the number of pecks issued to the elements was important for numerosities above 2. An additional test confirmed that the birds chose the symbol that corresponded to a particular numerosity rather than the positions that the symbols had held during training.     

The pigeon's discrimination of movement patterns (Lissajous figures) and contour-dependent rotational invariance

The ability of pigeons to discriminate complex motion patterns was investigated with the aid of moving Lissajous figures. The pigeons successfully learned to differentiate two successively presented cyclic trajectories of a single moving dot. This suggests that they can recognize a movement Gestalt when information about shape is minimal. They also quickly learned a new discrimination between moving-outline stimuli with repetitively changing contour patterns. Contrasting results were obtained when the dot or outline stimuli were axis-rotated through 90 degrees. Rotational invariance of pattern discrimination was clearly demonstrated only when moving contours were visible. Nevertheless, pigeons could discriminate the axis-orientation of a moving-dot or moving-outline pattern when trained to do so. Discrimination did not seem to depend on single parameters of motion but rather on the recognition of a temporally integrated movement Gestalt. The visual system of pigeons, as well as that of humans, may be well adapted to recognize the types of oscillatory movements that represent components of the motor behaviour shown by many living organisms.

Does Language Affect Personality Perception? A Functional Approach to Testing the Whorfian Hypothesis

Whether language shapes cognition has long been a controversial issue. The present research adopts a functional approach to examining the effects of language use on personality perception and dialectical thinking. We propose that language use activates corresponding cultural mindsets, which in turn influence social perception, thinking, and behavior. Four studies recruited Chinese‐English bilinguals (N = 129 in Study 1, 229 in Study 2, 68 in Study 3, 106 in Study 4) and used within‐subjects and between‐subjects design, written and behavioral reports, and self‐ and other perceptions. The four studies converged to show that Chinese‐English bilinguals exhibit higher dialectical thinking and more variations in self‐ and observer ratings of personality when using the Chinese language than when using English. Furthermore, dialectical thinking predicted more self‐ and other‐perceived variations in personality and behavior across bilingual contexts. These results highlight the important role of culture in understanding the relations between language and cognition, and attest to the malleability of personality perception and dialectical thinking within and across individuals in response to culture‐related linguistic cues.     

Unraveling the Wonder of the Ordinary: A Narrative Analysis of Meaning Construction in Memories of Familiar Routines

Familiar routines may be a source of meaning, but just as well become habitual and lose meaning. To understand this paradox, a narrative approach was used to explore how meaning is constructed in memories of familiar routines. Two types were distinguished: routines of transition and routines of harmony. Results show how meaning construction may relate to the contrast between instrumental acts in the memories and their higher purpose. In routines of transition, meaning may emerge through a temporal transformation, while routines of harmony may become meaningful through the awareness of contrasting evaluations within the routine or a contrasting wider context.     

Effects of dilemma type,language, and emotion arousal on utilitarian vs deontological choice to moral dilemmas in Chinese–English bilinguals

The present study examines how dilemma type (personal or impersonal moral dilemma), language (native or foreign) and emotion arousal to a dilemma could affect Chinese–English bilinguals' deontological vs utilitarian moral choices regarding 39 moral dilemmas. How emotion arousal plays a mediating role in the effects of dilemma type and language on moral choices is also investigated. As shown in multilevel analyses, participants made fewer utilitarian choices for personal dilemmas than impersonal dilemmas. Although emotion arousal of dilemmas significantly mediated this effect of dilemma type, the indirect effect of dilemma type through arousal on moral choices was inconsistent with the direct effect of dilemma type on moral choices. For the effect of language, participants made more utilitarian choices in the Footbridge (personal) dilemma that was presented in foreign language than in native language. However, this effect was not mediated by arousal, suggesting that it could not be attributed to the emotion‐reducing effect of foreign language. Moreover, there was no language effect on moral choices in analyses that included all 39 dilemmas or only 22 personal dilemmas, indicating the need in future research for further identifying the potential mediators that trigger the foreign language effect on moral choices.     

Organizational Decision-making in the Appropriation of Technological Innovation: Cognitive and Political Dimensions

Abstract

Outcomes of innovation may depend upon the user's decision processes in its appropriation. The context for the user's decision-making comprises three interdependent elements: (1) the innovation pool; (2) the user; and (3) the supplier of the innovation. User decisions are seen as a series of four interlocking decision episodes. During the first two episodes (agenda formation and selection) the problem is defined and a solution chosen. In the latter two episodes (implementation and usage) the innovation is adopted and used. Appropriation may depend on dual modification of the innovation and organizational practices until the innovation meets the unique requirements of the user. Cognitive and political variables relevant to technological innovation are suggested and explored by drawing upon qualitative comparisons across seven cases of technological innovation in British manufacturing firms. Particular problems occur when users have inadequate knowledge bases, overuse heuristics and analogies, and have conflicting beliefs about the chosen innovation. The extent to which cognitive variables impose on success with the innovation may be mediated by political processes, and may also interact with national culture. Focus is on the processes during the early episodes of agenda formation and selection on the grounds that problems engendered here carry over to implementation.
