The experimental task influences cue competition in human causal learning

Participants were shown A+ and C- trials followed by AB+ and CD+ trials. These trials were embedded in a causal learning task in which participants had to learn either the relationship between different foods and allergic reactions or the relationship between different stocks and an increase in the stock market index. The authors orthogonally varied the manner in which the different cues were presented to participants during training. Cue competition was related to the causal learning scenario but not to the manner in which the different cues were presented. These results question claims of a human bias toward configural processing that were based on difficulties in finding cue competition in some previous causal learning experiments.     

Retrieval of incidental stimulus-response associations as a source of negative priming

Priming effects of ignored distractor words were investigated in a task-switching situation that allowed an orthogonal variation of priming and response compatibility between prime and probe. Across 3 experiments, the authors obtained a disordinal interaction of priming and response relation. Responding was delayed in the ignored repetition condition if different responses were required for identical stimuli in the prime and probe (negative priming). Repeating the prime distractor in the probe facilitated responding if the same response was required in the prime and in the probe (positive priming). The same pattern of results was replicated in a letter-matching task without task switching (Experiment 4). Findings lend support to a new model that explains negative priming in terms of an automatic retrieval of incidental stimulus-response associations.     

Agonistic screams in wild chimpanzees (Pan troglodytes schweinfurthii) vary as a function of social role

Some nonhuman primates have demonstrated the capacity to communicate about external objects or events, suggesting primate vocalizations can function as referential signals. However, there is little convincing evidence for functionally referential communication in any great ape species. Here, the authors demonstrate that wild chimpanzees (Pan troglodytes schweinfurthii) of Budongo forest, Uganda, give acoustically distinct screams during agonistic interactions depending on the role they play in a conflict. The authors analyzed the acoustic structure of screams of 14 individuals, in the role of both aggressor and victim. The authors found consistent differences in the acoustic structure of the screams, across individuals, depending on the social role the individual played during the conflict. The authors propose that these 2 distinct scream variants, produced by victims and aggressors during agonistic interactions, may be promising candidates for functioning as referential signals.     

The facial pattern of disgust, appetence, excited joy and relaxed joy: an improved facial EMG study

The purpose of the study was to investigate the facial muscle pattern of disgust in comparison to appetence and joy, using an improved facial EMG method. We analyzed the activity of nine facial muscles in forty healthy subjects. The subject group was randomly divided into two groups (oversaturated vs. hungry) of ten women and ten men each. Four different emotions (disgust, appetence, excited-joy and relaxed-joy) were induced by showing pictures from the IAPS. Pre-visible facial muscle activity was measured with a new facial EMG. A Visual Analog Scale (VAS) was established. Disgust is represented by a specific facial muscle pattern involving M.corrugator and M.orbicularis oculi, clearly distinguishing it from the facial patterns of appetence and joy. The intensity of disgust is stronger in a state of hunger than under oversaturation and is altogether stronger in females than in males. Our findings indicate the possibility to explore the entire emotion system successfully through a state-of-the-art psychophysiological method like our EMG device.     

The effects of muscle tension on cerebral circulation in blood-phobic and non-phobic subjects

This study aimed to assess whether (1) a muscle tensing procedure which has been found to be useful in the treatment of blood-phobic patients produces an increase in heart rate and cerebral blood flow and (2) whether this increase is greater than that produced by mental effort alone. Subjects were 17 volunteers with a history of fainting in response to blood-injury stimuli, (12 were phobic) and 8 volunteers with no fainting history. They were required to (a) rest, (b) do mental arithmetic, and (c) repeatedly tense and release their arm and leg muscles. It was found that Ss, heart rate and cerebral blood flow velocity were significantly greater during the muscle tensing procedure than during mental arithmetic or resting conditions. The increased cerebral blood flow produced by muscle tensing may enable blood phobic patients to prevent fainting during exposure treatment.     

Potential pitfalls in computational modelling of appraisal processes: A reply to chwelos and oatley

Abstract

This paper extends the discussion on computational approaches towards modelling emotion antecedent appraisal processes, based on Scherer (1993a) and Chwelos and Oatley (1994). In the first part we briefly discuss the different goals that motivate such modelling as well as potential pitfalls. We then take up some of the critiques of GENESE expressed by Chwelos and Oatley, and examine the proposed alternatives. The paper concludes with an outline of perspectives for future work in this domain.     

Political Psychology as Applied Psychology: An Introduction

On souligne, dans I'introduction du numéro spécial d' Applied Psychology: An International Review sur la Psychologie Politique, qu'il existe deux courants parmi les contributions au champ de la psychologie politique. L'un traite des implications politiques en jeu quand la politique est utilisée pour illustrer des problématiques psychologiques. L'autre est une « Psychologie Politique politique >> où les orientations des Sciences Politiques définissent les problématiques. La seconde partie de l'introduction montre que cette discipline emprunte largement à trois grandes théories de la psychologie (la théorie cognitive, la théorie de I'apprentissage et la psychanalyse) et que la plupart des publications abordent des thèmes en rapport avec les psychologies sociale, clinique, de la personnalité et du développement. Enfin, les sept contributions émanant d'auteurs de quatre continents sont brièvement introduites.
The introduction to Applied Psychology: An International Review's special issue on Political Psychology argues that there are two streams of contributions to the field of political psychology. One is work with political implications where politics are used to illustrate psychological research questions. The other is a "political Political Psychology" where the agenda of political science defines the research questions. A second part of the introduction shows that the discipline draws most heavily on three grand theories of psychology, namely cognitive theory, psychoanalysis, and learning theory with most publications working on questions related to social psychology, personality, clinical, and developmental psychology. Finally the seven contributions by authors from four continents are briefly introduced.
