The Effects of Alcohol Intoxication on Accuracy and the Confidence–Accuracy Relationship in Photographic Simultaneous Line‐ups

Acute alcohol intoxication during encoding can impair subsequent identification accuracy, but results across studies have been inconsistent, with studies often finding no effect. Little is also known about how alcohol intoxication affects the identification confidence–accuracy relationship. We randomly assigned women (N = 153) to consume alcohol (dosed to achieve a 0.08% blood alcohol content) or tonic water, controlling for alcohol expectancy. Women then participated in an interactive hypothetical sexual assault scenario and, 24 hours or 7 days later, attempted to identify the assailant from a perpetrator present or a perpetrator absent simultaneous line‐up and reported their decision confidence. Overall, levels of identification accuracy were similar across the alcohol and tonic water groups. However, women who had consumed tonic water as opposed to alcohol identified the assailant with higher confidence on average. Further, calibration analyses suggested that confidence is predictive of accuracy regardless of alcohol consumption. The theoretical and applied implications of our results are discussed.© 2017 The Authors Applied Cognitive Psychology Published by John Wiley & Sons Ltd.     

Emotional Distress Associated with Surgical Treatment and its Relationship with Coping Profiles Among Chronically ill Older Patients

The study determines the patterns of coping styles among older patients with hip osteoarthritis and assesses the derived profiles in terms of perceived stress and anxiety before and after arthroplasty. Sixty-one hospital patients (mean age 70.3 years) were analysed one day before arthroplasty and three months after. The participants were assessed with the Brief-COPE (coping style), PSS-10 (perceived stress) and STAI (anxiety) psychometric tests. Four coping patterns were yielded using data clustering: rational, enterprising (resourceful), potentially maladaptive and flexible. Repeated measures ANOVA indicated a main effect within subjects but did not indicate that decreases of stress and anxiety varied differently between groups. Cluster 1 (a coping profile characterised by high helplessness, low active coping, high avoidance) reported significantly greater stress and anxiety than all other groups before and after hip replacement, while clusters 2 (flexible), 3 (resourceful) and 4 (rational) were characterised by similar levels of anxiety and stress. Older patients with osteoarthritis might differ in terms of emotional response to surgical treatment. Screening for coping styles at admission to hospital may indicate more vulnerable individuals.     

“May I present you: my disgust!” – Declared disgust sensitivity in the presence of attractive models

Disgust sensitivity differs among men and women, and this phenomenon has been observed across numerous cultures. It remains unknown why such sex differences occur, but one of the reasons may relate to differences in self-presentation. We tested that hypothesis in an experiment comprising 299 participants (49% women) randomly allocated into three groups. Each group completed the Three Domains Disgust Scale (TDDS) and rated how disgusting they found olfactory, visual, gustatory, and tactile disgust elicitors either when a male experimenter was present, a female experimenter was present, or no experimenter was present. We hypothesised that male participants in the female experimenter group would declare decreased levels of disgust sensitivity, and female participants in the male experimenter group would declare increased levels of disgust sensitivity. Results showed that despite sex differences in pathogen and sexual disgust, attractive experimenters did not evoke any differences in declared disgust across groups with one exception–both men and women self-presented as more sensitive to sexual disgust in the presence of the female experimenter. We discuss our findings in the light of evolutionary and social theories.     

Finger flexor motor control patterns during active flexion: an in vivo tendon force study

An in vivo tendon force measurement system was used to evaluate index finger flexor motor control patterns during active finger flexion. During open carpal tunnel release surgery (N=12) the flexor digitorum profundus (FDP) and flexor digitorum superficilias (FDS) tendons were instrumented with buckle force transducers and participants performed finger flexion at two different wrist angles (0 degrees or 30 degrees ). During finger flexion, there was concurrent change of metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint angles, but the FDP and FDS tendon force changes were not concurrent. For the FDS tendon, no consistent changes in force were observed across participants at either wrist angle. For the FDP tendon, there were two force patterns. With the wrist in a neutral posture, the movement was initiated without force from the finger flexors, and further flexion (after the first 0.5s) was carried out with force from the FDP. With the wrist in a flexed posture, the motion was generally both initiated and continued using FDP force. At some wrist postures, finger flexion was initiated by passive forces which were replaced by FDP force to complete the motion.     

The Lattice of Subvarieties of the Variety Defined by Externally Compatible Identities of Abelian Groups of Exponent <Emphasis Type="Italic">n</Emphasis>

The lattices of varieties were studied in many works (see [4], [5], [11], [24], [31]). In this paper we describe the lattice of all subvarieties of the variety defined by so called externally compatible identities of Abelian groups and the identity x ⁿ ≈ y ⁿ . The notation in this paper is the same as in [2]. Presented by W. Dziobiak     

BASIC RELATIONS IN CHILD LANGUAGE AND THE WORD ORDER MYTH

The research involved an evaluation of the psychological reality of the syntactic functions of subject and object, the semantic functions of agent and patient, and the discourse functions of given and new. The domain of analysis was from the early two-word into the early three-word phase (approximately 1;7 to 2;5) of the acquisition of the relatively synthetic language of Polish. An analysis of the inflectional morphology revealed the appropriate use of all seven cases and contrasts within three dimensions of agreement before 1;9. These varied inflectional forms were used with sufficient frequency to argue that the nominative case and the agreement relations are productive subjecthood properties at this phase of development. The semantic function of the subject noun phrase was either an agent or a patient. Hence, case and agreement cannot be reduced to properties of semantic functions. Since both subject and object were rarely realized simultaneously in the surface structure in the early phase of two word utterances, the set of verb plus subject and verb plus object patterns (i.e., SV, VS, OV, and VO) were analyzed for the discourse functions of given and new. Neither discourse function nor cannonical (SV and VO) form control word order. As both subject and object came to be realized in the surface structure, subject before object priority was revealed as a subjecthood property but not in a rigid word order (i.e., both SVO and SOV patterns occurred). The evidence demonstrates the independent status of the syntactic function of subject.     

A Note on Matrices for Systems of nonsense-logics

We construct a class K of algebras which are matrices of the logical system Z introduced in [4]. It is shown that algebras belonging to the class K are decomposable into disjoint subalgebras which are Boolean algebras.To the memory of Jerzy SupeckiTranslated From the Polish by Jan Zygmunt.     

Where’s the cookie? The ability of monkeys to track object transpositions

Object permanence is the ability to represent mentally an object and follow its position even when it has disappeared from view. According to Piaget’s 6-stage scale of the sensorimotor period of development, it seems that object permanence appears in Stage 4 and fully develops in Stage 6. In this study, we investigated the ability of some species of monkeys (i.e. pig-tailed macaque, lion-tailed macaque, Celebes crested macaque, barbary macaque, De Brazza’s monkey, L’Hoest’s monkey, Allen’s swamp monkey, black crested mangabeys, collared mangabeys, Geoffroy’s spider monkey) to track the displacement of an object, which consisted of a reward hidden under one of two cups. Our findings showed that the examined subjects possess Stage 6 of object permanence. We then compared our results with data on apes and dogs participating in Rooijakkers et al. (Anim Cogn 12:789–796, 2009) experiment, where the same method was applied. The monkeys examined by us performed significantly better than the dogs but worse than the apes. In our experiment, the monkeys performed above chance level in all variants, but it should be noted that we observed significant differences in the number of correct choices according to the level of a variant’s complexity.     

The detour paradigm in animal cognition

In this paper, we review one of the oldest paradigms used in animal cognition: the detour paradigm. The paradigm presents the subject with a situation where a direct route to the goal is blocked and a detour must be made to reach it. Often being an ecologically valid and a versatile tool, the detour paradigm has been used to study diverse cognitive skills like insight, social learning, inhibitory control and route planning. Due to the relative ease of administrating detour tasks, the paradigm has lately been used in large-scale comparative studies in order to investigate the evolution of inhibitory control. Here we review the detour paradigm and some of its cognitive requirements, we identify various ecological and contextual factors that might affect detour performance, we also discuss developmental and neurological underpinnings of detour behaviors, and we suggest some methodological approaches to make species comparisons more robust.     

Social class and interpersonal trust: Partner's warmth,external threats and interpretations of trust betrayal

The present research investigated the effects of social class on interpersonal trust. In a series of experiments, we showed how the contextualist socio-cognitive tendencies of the lower class and the solipsistic tendencies of the upper class were reflected in their trusting attitudes and behaviors. In Study 1 (N = 491), upper class individuals expressed the same levels of trust towards all partners, while lower class individuals adjusted their trust choices to the affect-rich information about their interaction partner and trusted warm partners more than cold partners. The results of Study 2 (N = 210) showed that when threatened, lower class individuals had generally less trusting attitudes, while upper class members were equally trusting as in a neutral situation. Study 3 (N = 200) revealed that upper class individuals explained a betrayal of their trust with dispositional factors to a higher degree than lower class individuals. We discuss how these differences contribute to perpetuating the disadvantage of the lower class.
