Human left-sided cradling preferences for dogs

Photographs of men and women holding dogs were analyzed for side-holding preferences. A significant majority of women in dog-themed magazines held dogs on their left sides, similar to reports of women holding infants. Men did not show the same left-sided preference, which is also consistent with other studies. The implications of these results for various hypotheses about infant cradling behavior were discussed.     

Mimicking disliked others: Effects of a priori liking on the mimicry‐liking link

The sharing of bodily states elicits in mimicker and mimickee corresponding conceptualisations, which facilitates liking. There are many studies showing the relatedness of mimicry and liking. However, the mimicry‐liking link has not been investigated under conditions in which the mimickee is liked or disliked a priori. In two studies, we examined moderating effects of a priori liking on the mimicry‐liking link. Liking was measured via self‐report measures (Studies 1 and 2) and behavioural measures using a virtual environment technology (Study 2). Results showed that when participants intentionally mimicked a disliked person, liking for that person was not improved, whereas when participants mimicked a liked person, liking for that person increased. These effects were shown to be mediated by affiliation. These studies not only provided further evidence of a link between mimicry and liking, but also demonstrated that this relationship is moderated by a priori liking.

Collaborative recall of details of an emotional film

Collaborative inhibition refers to the phenomenon that when several people work together to produce a single memory report, they typically produce fewer items than when the unique items in the individual reports of the same number of participants are combined (i.e., nominal recall). Yet, apart from this negative effect, collaboration may be beneficial in that group members remove errors from a collaborative report. Collaborative inhibition studies on memory for emotional stimuli are scarce. Therefore, the present study examined both collaborative inhibition and collaborative error reduction in the recall of the details of emotional material in a laboratory setting. Female undergraduates (n = 111) viewed a film clip of a fatal accident and subsequently engaged in either collaborative (n = 57) or individual recall (n = 54) in groups of three. The results show that, across several detail categories, collaborating groups recalled fewer details than nominal groups. However, overall, nominal recall produced more errors than collaborative recall. The present results extend earlier findings on both collaborative inhibition and error reduction to the recall of affectively laden material. These findings may have implications for the applied fields of forensic and clinical psychology.     

The logic of conditionals 1

The standard use of the propositional calculus ('P.C.’) in analyzing the validity of inferences involving conditionals leads to fallacies, and the problem is to determine where P.C. may be ‘safely’ used. An alternative analysis of criteria of reasonableness of inferences in terms of conditions of justification rather than truth of statements is proposed. It is argued, under certain restrictions, that P. C. may be safely used, except in inferences whose conclusions are conditionals whose antecedents are incompatible with the premises in the sense that if the antecedent became known, some of the previously asserted premises would have to be withdrawn.     

Differential Reactions of Patients Receiving Group Psychotherapy with Concomitant Somatic and Drug Therapies

The embeddedness of combat aggression, violence, survival, and antiauthority dynamics in the psychic organization of Vietnam veterans in groups shape the treatment enterprise. Inherent in treatment interactions and dynamic processes of the Vietnam therapy group are the reactivations of Vietnam-historical reenactments. These involve strong affective reactions toward superiors and toward fellow combatants (“grunts”), with an attendant sense of group danger, unconsciously reminiscent of Vietnam's guerrilla war terrain. This paper notes that because of the tendency of the group to repeat actual events (as opposed to fantasied events), these groups require divergent conceptualizations and technical management. An innovative model comprising a series of developmental phases is presented. This model, called “the curvilinear regressive-progressive model” of treatment with Vietnam veterans, focuses on both peer- and leader-centered dynamics in working through guilt-driven defenses in members. The leader plays a pivotal function in monitoring levels of affect tolerance in the group, and is expected to manage countertransference reactions, and to have sensitivity to the effects of combat stress on self structure. As the Vietnam therapy group members relive the history of the Vietnam conflict in the group, the leader utilizes a flexible, phase-sensitive system of interventions to reactivate arrested development by creating a healing climate where developmental tasks can be mastered and integrated by group members.     

Subjectivity and environmentalism

The main thesis of this paper is that the most cogent demands of subjectivity, at least with respect to questions concerning the contents of our thoughts, can be accommodated within an objectivist framework. I begin with two theses: (1) Subjectivity: I can know (the contents of) my own thoughts without appeal to any knowledge of features external to my mind; (2) Environmentalism: (The contents of) my thoughts are determined by features external to my mind, at least in this sense: without causal and/or social interaction between my internal states and various external features, these internal states would not have the particular contents they have and therefore would not be the mental states they are. Section I proceeds by elucidating various lines of environmentalism, an overtly objectivist thesis. Section II considers and refutes one purported environmentalist challenge to subjectivity, namely, that, according to it, thoughts are not in the head. Section III discusses a central subjectivist thesis, namely, thoughts do not admit of an appearance/reality distinction. Tyler Burge and Hilary Putnam, two environmentalists, seem to endorse such a distinction. It is argued that the two most reasonable routes of escape open to them require a retreat from environmentalism. This leaves us with an apparent dilemma: reject either subjectivity or environmentalism Section IV defends environmentalism. Section V considers and criticizes a maneuver Donald Davidson makes to preserve first‐person authority over thought‐contents. Section VI concludes with a brief defense of environmentalism which rests largely on rejecting a deeply entrenched epistemic model about how we access our own thoughts. It is argued that it is this bad epistemic model and not subjectivity per se, which has created whatever tension there appears to be between subjectivity and environmentalism.     

Redundancy: A Similar Principle in Independent Adaptation Techniques

The present study examined the similarities between four auditory adaptation techniques to determine whether the effects were correlated. The four adaptation techniques compared were: Simultaneous Dichotic Loudness Balance technique (SDLB; Hood, 1950), Magnitude Estimated Binaural technique (MEB; Botté, Canévet, & Scharf, 1982), Magnitude Estimated Monaural technique, (MEM; Weiler, Sandman, & Pederson, 1981), and the Monaural Reaction Time technique (RT; Davis & Weiler, 1976). Results did not show significant correlations between the four techniques, except (r = 0.39) between MEB and MEM procedures. This correlation was much less than the reliability of the measures would allow (r = 0.98 and r = 0.99, respectively). Thus, it appears that the different methods either produced different adaptation effects or measured different aspects of auditory adaptation. The normal ear apparently shows several forms of adaptation, which reduces the perceptual strength of a continuing stimulus, in favor of an intermittent, less redundant one.     

Monaural Loudness Adaptation for Middle-Intensity Middle-Frequency Signals: The Importance of Measurement Technique

Using the Simple Adaptation technique (SA) and the Ipsilateral Comparison Paradigm (ICP), the authors studied monaural loudness adaptation to a middle-intensity [60 dB(A)] tone at signal frequencies of 250, 1000, and 4000 Hz in the left and right ears. Adaptation effects were absent when the SA procedure was used. However, they were observed uniformly across all frequency values with the ICP, a result that challenges the assertion in the literature, on the basis of SA measures, that loudness adaptation for middle-intensity signals occurs only at frequencies above 4000 Hz. The ICP features periodic intensity modulations (±10 dB relative to the base signal) to accommodate listeners' needs for referents by which they can gauge subtle changes in the loudness of the adapting tone, a key component that is missing in the SA method. Adaptation effects in this investigation were similar in both ears, supporting the equal susceptibility assumption common in loudness adaptation studies.     

Power Spectral Density Analysis of Lateral Human Standing Sway

A number of investigators have used power spectral density (PSD) analysis to try to identify and quantify various sensory systems which are involved in upright standing. Using PSD analysis, over a frequency range from 0.02-2.5 Hz, the present study examined two trials of lateral sway in each of 80 men. The results showed that little change occurred in PSD values between the first and second trials. Exponential curves were fit to the averaged trials data of each subject. The values of the parameter estimates obtained from the curve-fitting were regressed on the values of various direct, and derived anthropometric variables to try to explain the variance of the parameter estimates in terms of the anthropometrics. The subject’s center of gravity location accounted for no more than 15.8% of the parameter variance, whereas the remaining anthropometrics explained even less. The overall averaged data suggest that three functions (related to visual, vestibular, and proprioceptive processes) may underlie the sway pattern over this frequency range. PSD curves of individuals with a history of high-level athletic activity clearly differed from those of sedentary subjects.
