Forgoing Debriefing in Deceptive Research: Is It Ever Ethical?

The use of deception in research is generally permitted so long as participants are debriefed at the conclusion of their participation. Several authoritative research ethics guidelines allow investigators to omit debriefing under certain circumstances, however. Here we examine various justifications for forgoing debriefing in deceptive research, including concerns about subject pool contamination, the risk that revealing the deception will be harmful or distressing to participants, and issues of practicability. We conclude that, contrary to current practice, omitting debriefing is ethically acceptable only when debriefing is impracticable, the deception is innocuous, and no reasonable person would object to involvement in the research.     

Further Evidence Concerning Motivational Distortion on the Sixteen Personality Factor Primaries by Male Felons

A multiple regression analysis was used to determine the susceptibility of the 16 Personality Factor Test (16PF) to faking for a sample of male felons. The study is a replication of an earlier study of a similar sample. Motivational distortion (MID) correlated significantly with the 16 PF primary scores. The relationship was most evident when the structure coefficients rather than the beta weights were analyzed. The findings were consistent with the previous results which indicated a fairly high degree of support for the MD corrections provided in the manual. An important exception was that Dominance (E) was suppressed by individuals from both samples when MD was present.     

The Present Status of the Frontal Lobe

This study contrasted two models of prospective remembering: i.e., remembering in the future to perform an action that has been planned. High anxiety or discomfort is predicted by the first model to be associated with forgetting, and by the second model to be associated with remembering but not performing. Questionnaire data from 73 male and female college students support the second model (p < .01). For planned actions that were forgotten, there was an inverse relationship between importance and comfortableness (p < .01). Prospective remembering may be facilitated by reducing potential conflict between the importance and comfortableness of a planned action, involving other persons, and utilizing external retrieval cues.     

Emotional expression affects the accuracy of gaze perception

Emotional facial expressions are powerful social cues. Here we investigated how emotional expression affects the interpretation of eye gaze direction. Fifty-two observers judged where faces were looking by moving a slider on a measuring bar to the respective position. The faces displayed either an angry, happy, fearful or a neutral expression and were looking either straight at the observer, or were rotated 2°, 4°, 6° or 8° to the left and right. We found that happy faces were interpreted as directed closer to the observer, while fearful and angry faces were interpreted as directed further away. Judgments were most accurate for neutral faces, followed by happy, angry and fearful faces. These findings are discussed on the background of the “self-referential positivity bias”, suggesting that happy faces are preferably interpreted as directed towards the self while negative emotions are interpreted as directed further away.     

Resurrecting the tracking theories

Much of contemporary epistemology proceeds on the assumption that tracking theories of knowledge, such as those of Dretske and Nozick, are dead. The word on the street is that Kripke and others killed these theories with their counterexamples, and that epistemology must move in a new direction as a result. In this paper we defend the tracking theories against purportedly deadly objections. We detect life in the tracking theories, despite what we perceive to be a premature burial.     

Certain Emotional Factors in Learning and Efficiency

A group of measures duplicating the original battery of tests which Halstead used to obtain his four biological intelligence factors were given to a group of subjects with acute lateralized brain lesions. These results were compared to the results of the same battery when administered to subjects with chronic diffuse brain damage. This comparison demonstrated that the factors derived from brain damage testing are affected by (a) the subjects' mental abilities, (b) the sensitivity of the measures to brain damage in general, and (c) the lateralization of the damage.     

Loudness counts: Interactions between loudness,number magnitude,and space

ATOM (a theory of magnitude) suggests that magnitude information of different formats (numbers, space, and time) is processed within a generalized magnitude network. In this study we investigated whether loudness, as a possible indicator of intensity and magnitude, interacts with the processing of numbers. Small and large numbers, spoken in a quiet and a loud voice, were simultaneously presented to the left and right ear (Experiments 1a and 1b). Participants judged whether the number presented to the left or right ear was louder or larger. Responses were faster when the smaller number was spoken in a quiet voice, and the larger number in a loud voice. Thus, task-irrelevant numerical information influenced the processing of loudness and vice versa. This bi-directional link was also confirmed by classical SNARC paradigms (spatial–numerical association of response codes; Experiments 2a–2c) when participants again judged the magnitude or loudness of separately presented stimuli. In contrast, no loudness–number association was found in a parity judgment task. Regular SNARC effects were found in the magnitude and parity judgment task, but not in the loudness judgment task. Instead, in the latter task, response side was associated with loudness. Possible explanations for these results are discussed.     

Beyond pluralism: psychoanalysis and the workings of mind

Subjects that Freud excluded or incompletely explored have been sites of theoretical expansion in over a century of observation: the role of the other, the self, the preoedipal period, action, the countertransference, limits to neutrality/anonymity/abstinence, the loci of the analytic drama, effects beyond interpretation, agency, and basic needs (versus wishes). These developments have led to conflicting theories and sect-like groupings within the field. Group psychological processes underlying this are discussed; and a broad and inclusive view of psychoanalysis is proposed under the heading of the study of the workings of mind. Additionally, substantial integrative proposals are offered with respect to the central tasks of individual development, theories of mind, the relational turn, and aspects of technique.     

Classical conditioning of autonomic fear responses is independent of contingency awareness

The role of contingency awareness in classical conditioning experiments using human subjects is currently under debate. This study took a novel approach to manipulating contingency awareness in a differential Pavlovian conditioning paradigm. Complex sine wave gratings were used as visual conditional stimuli (CS). By manipulating the fundamental spatial frequency of the displays, we were able to construct pairs of stimuli that varied in discriminability. One group of subjects was given an "easy" discrimination, and another was exposed to a "difficult" CS+ and CS-. A 3rd group was exposed to a stimulus that was paired with the unconditional stimulus (UCS) 50% of the time and served as a control. Skin conductance response (SCR) and continuous UCS expectancy data were measured concurrently throughout the experiment. Differential UCS expectancy was found only in the easy discrimination group. Differential SCRs were found in the easy discrimination group as well as in the difficult discrimination group, but not in the 50% contingency control. The difficult discrimination group did not exhibit differential UCS expectancy but did show clear differential SCR. These observations support a dual process interpretation of classical conditioning whereby conditioning on an implicit level can occur without explicit knowledge about the contingencies.

Trinity Talk, Again

Abstract :  The doctrine of the Trinity has, in the past couple of decades, reclaimed its central place in Christian God talk. Theologians are now using it to render every doctrine more explicitly Christian, and to sharpen interreligious dialogue. There is a strong drive toward vindicating the doctrine as relevant, but also a recognition that if it is truly a teaching about God it must remain somewhat theoretical. Finally, the field of historical theology is undertaking a fresh examination of the basic primary texts of trinitarian theology.
