“Put a Little Love in Your Heart”: Acceptance of Paternalistic and Ally Political Discourses Both Predict Pro-Roma Solidarity Intentions Through Moral Inclusion

The way politicians talk about minorities institutes the normative context of intergroup relations. We investigated how endorsement of different political discourses predicts donation and collective action intentions by majority members toward the Roma in five European countries. The survey was conducted online using samples demographically similar to the populations of Hungary, Slovakia, Romania, France, and Ireland (N = 5,054). First, results showed that accepting paternalistic discourse versus discourse promoting allyship were not distinguishable; both promoted higher moral inclusion which in turn predicted higher prosocial intentions. Second, donations (i.e., immediate relief) and collective action (i.e., social change action) were driven by identical factors. Third, acceptance of openly hostile political discourse neither predicted moral exclusion, nor lower prosocial intentions. In summary, our research provides important evidence that when it comes to Roma—non-Roma relations, the previously established distinction between solidarity intentions that aim to solidify status relations versus bring about social change is completely blurred, presumably because of the social context in which any positive message communicates moral inclusion challenging the hostile status quo.     

Probability of directional errors with disordinal (qualitative) interaction

In a factorial design with two or more factors, there is nonzero interaction when the differences among the levels of one factor vary with levels of other factors. The interaction is disordinal or qualitative with respect to a specific factor, sayA, if the difference between at least two levels ofA is positive for some and negative for some levels of the other factors. Using standard methods of analysis, there is a potentially large probability of drawing incorrect conclusions about the signs of differences in the presence of disordinal interaction. The maximum probability of such incorrect conclusions, or directional errors, is derived for two-factor designs in which the factor of interest has two levels and the number of levels of the other factor varies.     

Leadership and Social Identification in Military Units: Direct and Indirect Relationships1

This study examines some antecedents and consequences of social identification in military units. Data were collected from 2 samples in each unit: staff members and soldiers. It was found that identification with the unit was related to 3 categories of leader behavior: an emphasis on collective identity, an emphasis on shared values, and inclusive behaviors. Some of the effects of leader behaviors on members' social identification were mediated by their effects on unit culture. Some of the effects of leader behaviors on the social identification of more distant subordinates (soldiers) were mediated by their effects on the social identification of closer subordinates (staff members). Differential effects of leader behaviors on the 2 levels of subordinates were also discovered.     

An evaluation of methods for behavioral investigations of teleost audition

Auditory thresholds have been determined for the goldfish by six groups of workers and the data in the experiments varied by as much as 20–30 dB. In order to isolate the basis for this variability, auditory thresholds were determined using conditioned suppression of respiration and method of limits. These thresholds were very similar to those obtained with avoidance conditioning and a tracking method for threshold determination. Acoustic procedures were kept constant in the two series of experiments, and it appears that wide variation in auditory thresholds for goldfish shown in different experiments is due to acoustic conditions in the experiments.     

Age differences in acquisition and retention of one-way avoidance learning in C57BL/6NNia and autoimmune mice

Acquisition and 48-h retention of a step-up active avoidance response were studied in separate age groups of C57BL/6NNia mice (aged 1.5, 3.5, 6, 12, or 26 months) and five strains of genetically autoimmune mice differing in life span. The C57BL/6NNia mice showed no change in ability to acquire the avoidance response between 1.5 and 3.5 months, but showed a steady decline in that ability thereafter. Mouse strains with early-onset autoimmune disorder (NZB/B1NJ, MRL/MpJ-lpr, and BXSB/MpJ) showed declines in acquisition capability between 1.5 and 3.5 months of age, whereas mouse strains with mild, late-onset autoimmune disorder (MRL/MpJ- + and NZBWF1/J) showed stable or improved acquisition during that period. Both the C57BL/6NNia and NZB/B1NJ mice showed age-dependent declines in 48-h retention performance by 12 months of age. These findings suggested that while 48-h retention performance deficits were most related to chronological age, avoidance acquisition deficits were related to development of autoimmunity.     

The Development of Charismatic Leaders

This paper explores the origins of leadership potential and motivation for leadership, primarily with regard to two types of leaders: personalized and socialized charismatic leaders. Bowlby's attachment theory (1969, 1973) provides a theoretical basis for determining an individual's potential to be in leadership positions. The "internal working model," formed (according to Bowlby) in the course of attachment processes in infancy, has a considerable impact on self-perception, which may later affect the development of "ego resources" required for leadership. The motivation to be a leader is analyzed with the help of various psychodynamic concepts and models.     

An automated positive reward method for measuring acoustic sensitivity in fish

A microcomputer-controlled positive reward operant conditioning paradigm was developed to measure auditory sensitivity of the goldfish (Carassius auratus). Although other procedures have been used to measure hearing sensitivity in fish, all earlier studies have been done with some form of aversive conditioning. Goldfish were trained with a positive reinforcement method to determine hearing thresholds at 200, 500, 1000, 1500, and 2000 Hz. The audiogram obtained in this study is in close agreement with thresholds obtained with instrumental avoidance and classical conditioning procedures involving negative reinforcement (shock). The similarity in threshold data validates the effectiveness of the positive reinforcement paradigm described here. The major advantages of the present paradigm are the following: (1) No physical punishment such as electric shock is used, and (2) the versatility of the system allows easy modification for a variety of experiments.
