Effects of menstrual cycle phase on aggression measured in the laboratory

This study investigated the effects of menstrual cycle phase on aggression in two groups of women, which differed in the severity of their self-reported perimenstrual symptoms. A low- and a high-symptom group were recruited using the Menstrual Distress Questionnaire (MDQ) to define the groups. Twenty-two subjects (11 low and 11 high symptom) participated across one menstrual cycle: during the premenstrual, menstrual, midfollicular, and ovulatory phases. The Point Subtraction Aggression Paradigm was used to assess aggression on each day of participation. There were three main findings; a) rates of aggressive responding did not vary across phases of the menstrual cycle; b) the high-symptom group emitted higher rates of aggressive responding across the menstrual cycle than did the low-symptom group; and c) rates of aggressive responding correlated with the MDQ's behavioral and psychological scales and not the somatic scales. These findings indicate that the menstrual cycle phase does not differentially affect this laboratory measure of aggression. The differences found between the two symptom groups parallel a few reports indicating that women who differ in retrospectively reported mood and behavioral changes related to their menstrual cycle also differ on a number of other psychometric measures.

Laboratory and questionnaire measures of aggression among female parolees with violent or nonviolent histories

Female parolees were recruited into a laboratory study to determine the relationship between their previous aggression history, questionnaire measures of aggression, and behavioral measures of aggressive responding using a laboratory methodology: the Point Subtraction Aggression Paradigm (PSAP). Subjects were assigned to a violent or nonviolent group based on their criminal history. Subjects participated in sessions in which they were given three response options: (1) nonaggressive responding that earned money, (2) aggressive responding that ostensibly subtracted money from another fictitious person and was defined as aggressive since it resulted in the ostensible delivery of an aversive stimulus (subtraction of money) to another person, and (3) escape responding that protected the subject's earnings from periodic subtractions initiated by the fictitious other person. Results indicated that the violent female parolees emitted significantly more aggressive responses than subjects in the nonviolent group. This study provides additional external validity as well as evidence for convergent and discriminant validity for PSAP laboratory measurement of human aggressive responding and extends these findings to female parolees. Comparisons to previously published data with male parolees showed that gender differences were found among violent but not nonviolent parolees. Aggr.

The link between mental rotation ability and basic numerical representations

Mental rotation and number representation have both been studied widely, but although mental rotation has been linked to higher-level mathematical skills, to date it has not been shown whether mental rotation ability is linked to the most basic mental representation and processing of numbers. To investigate the possible connection between mental rotation abilities and numerical representation, 43 participants completed four tasks: 1) a standard pen-and-paper mental rotation task; 2) a multi-digit number magnitude comparison task assessing the compatibility effect, which indicates separate processing of decade and unit digits; 3) a number-line mapping task, which measures precision of number magnitude representation; and 4) a random number generation task, which yields measures both of executive control and of spatial number representations. Results show that mental rotation ability correlated significantly with both size of the compatibility effect and with number mapping accuracy, but not with any measures from the random number generation task. Together, these results suggest that higher mental rotation abilities are linked to more developed number representation, and also provide further evidence for the connection between spatial and numerical abilities.     

Nature as therapist: Integrating permaculture with mindfulness- and acceptance-based therapy in the Danish Healing Forest Garden Nacadia

Nature-based therapy can be considered an umbrella term for a diverse range of psychotherapeutic and allied practices which integrate experiences and activities in nature as therapeutic means. The objective of this article is to describe the theoretical framework for nature-based therapy in a university-founded healing forest garden near Copenhagen, Denmark. The garden will offer a 10-week treatment for people who are on sick leave with stress-related illness. This article focuses on clarifying the integration between the psychotherapeutic and gardening aspects of the nature-based therapy. The psychotherapeutic aspects are based on mindfulness and an acceptance therapy, while the gardening aspects are highly inspired by permacultural principles and methods.     

Sweet taste preferences and experiences predict prosocial inferences, personalities, and behaviors

It is striking that prosocial people are considered "sweet" (e.g., "she's a sweetie") because they are unlikely to differentially taste this way. These metaphors aid communication, but theories of conceptual metaphor and embodiment led us to hypothesize that they can be used to derive novel insights about personality processes. Five studies converged on this idea. Study 1 revealed that people believed strangers who liked sweet foods (e.g., candy) were also higher in agreeableness. Studies 2 and 3 showed that individual differences in the preference for sweet foods predicted prosocial personalities, prosocial intentions, and prosocial behaviors. Studies 4 and 5 used experimental designs and showed that momentarily savoring a sweet food (vs. a nonsweet food or no food) increased participants' self-reports of agreeableness and helping behavior. The results reveal that an embodied metaphor approach provides a complementary but unique perspective to traditional trait views of personality.     

The regulatory benefits of high levels of affect perception accuracy: A process analysis of reactions to stressors in daily life

Individuals attuned to affective signals from the environment may possess an advantage in the emotion-regulation realm. In two studies (total n = 151), individual differences in affective perception accuracy were assessed in an objective, performance-based manner. Subsequently, the same individuals completed daily diary protocols in which daily stressor levels were reported as well as problematic states shown to be stress-reactive in previous studies. In both studies, individual differences in affect perception accuracy interacted with daily stressor levels to predict the problematic outcomes. Daily stressors precipitated problematic reactions-whether depressive feelings (Study 1) or somatic symptoms (Study 2)-at low levels of affect perception accuracy, but did not do so at high levels of affect perception accuracy. The findings support a regulatory view of such perceptual abilities. Implications for understanding emotion regulation processes, emotional intelligence, and individual differences in reactivity are discussed.

Learning and development of embodied numerosity

Recent empirical evidence indicates that seemingly abstract numerical cognitions are rooted in sensory and bodily experiences. In particular in finger counting finger-based representations reflect a specific case of embodied cognition, we termed embodied numerosity. Furthermore, we suggest that finger-based representations should be considered a distinct representation of number (magnitude) and argue that this representation is activated automatically whenever we encounter a number. We discuss in what way such a theoretical framework can account for the associations of fingers and numbers observed so far. In the final part, we evaluate whether the concept of embodied numerosity should be generalized beyond finger-based representations with particular focus on whether bodily-sensory experiences (such as moving the whole body along the mental number line) may corroborate numerical capabilities. In a series of intervention studies, we consistently observed more pronounced training effects for our embodied numerosity trainings for different age groups, different digital media, different number ranges, and different control conditions. Taken together, we conclude that embodied representations of number (magnitude) exist, are not limited to finger-based representations, and influence number processing in a systematic and functional way that can be used to foster the efficiency of numerical trainings.     

Before and After the German Reunification: Changes in Observers' Commentaries on Achievements in a Natural Experiment1

East Germany (EG) and West Germany (WG) had been divided by the inner-German frontier for more than 4 decades. In 1989, the frontier fell, and in 1990, East and West Germany were reunified. To study differences in attributional patterns as a consequence of this political change, the attributions of WG TV-sport commentators during the 1988 and 1992 Olympic Games were analyzed for their frequency and antecedents. Results show an increase in internal and stable attributions after success in contrast to failure attributions; the former to a greater extent in 1992. In 1988 and in 1992, the positive achievements of EG athletes were attributed more often to internal causes than were the positive achievements of WG athletes. In 1992, attributions for EG athletes were more likely to be stable than in 1988.
