Reaching towards an end: Numerical end and distance effects in motor movements

Numerical comparisons are affected by the distance between the numbers and by the presence of an end stimulus. In line with embodied cognition approaches, past studies found evidence for the distance effect in continuous motor movements. The present study is the first to provide evidence for the end effect (i.e., faster comparisons for pairs that include an end stimulus of a set) using continuous motor movements. Two digits were presented horizontally on a screen and participants reached towards the larger one using a computer mouse cursor. Response trajectories were straighter (1) when the number pair included the end stimulus of 1, and (2) when the numerical distance between the numbers was large. Importantly, the end effect appeared earlier in the motor trajectory than the distance effect. The implications of this pattern for the cognitive processes underlying the end and the distance effects are discussed.     

Trauma Triangles and Parallel Processes: Geometry and the Supervisor/Trainee/Patient Triad

Relational psychoanalytic literature is filled with discussion regarding how the concept of intersubjectivity has enhanced the space between and within patients and analysts. As the relationship between the dyad expands and contracts, prior traumatic experiences become ripe for reenactment. What happens when the therapist is a trainee and her supervisor reenacts the abuse experienced by the patient onto her? When the enactment extends beyond the dyad and moves into the triad, how can the trainee use this shared experience to create agency for both herself and the patient? And how does the institutionalized authority of the training environment expand or collapse the transitional space required for trainees to create their own analyst identity? This paper explicates a case in which the trainee was able to use a rupture in the supervisory relationship to further enter the subjugated space of the patient, ultimately empowering both to develop a new way of relating to each other that moved them out of such constricted complimentary roles.     

Knowledge on the line: Manipulating beliefs about the magnitudes of symbolic numbers affects the linearity of line estimation tasks

It has been suggested that differences in performance on number-line estimation tasks are indicative of fundamental differences in people’s underlying representations of numerical magnitude. However, we were able to induce logarithmic-looking performance in adults for magnitude ranges over which they can typically perform linearly by manipulating their familiarity with the symbolic number formats that we used for the stimuli. This serves as an existence proof that individuals’ performances on number-line estimation tasks do not necessarily reflect the functional form of their underlying numerical magnitude representations. Rather, performance differences may result from symbolic difficulties (i.e., number-to-symbol mappings), independently of the underlying functional form. We demonstrated that number-line estimates that are well fit by logarithmic functions need not be produced by logarithmic functions. These findings led us to question the validity of considering logarithmic-looking performance on number-line estimation tasks as being indicative that magnitudes are being represented logarithmically, particularly when symbolic understanding is in question.     

Breaching the Contract: Aggressive Interpersonal Behaviors in Paternalistic Relationships

ABSTRACT

The study examined student evaluations (N?=?221) of frequency and impact of negative interpersonal behaviors by academic faculty and other students. As expected, negative behaviors by faculty was rated as less frequent but as more upsetting than those carried out by fellow students. The impact of such behaviors was not affected by the setting in which they occurred. However, students with a strong power motivation perceived negative behaviors by faculty as more upsetting than did students with a weak power motivation. The findings highlight the importance of covert restrictions on the exploitation of the potential power intrinsic in paternalistic relationships.     

From cleaning up to helping out: Parental socialization and children's early prosocial behavior

Relations between parental socialization and infants’ prosocial behavior were investigated in sixty three 18- and 30-month old children. Parents’ socialization techniques (e.g., directives, negotiation, reasoning) differed for the two age groups, as did relations between socialization and different forms of emerging prosocial behavior (helping; sharing).     

“Clamber not you up to the casements”: On ghetto views and viewing

On 29 March 1516 the Venetian Senate ordered all Jews residing in the city to move behind the walls of the ghetto. The mandate stipulated that Jews would be watched by Christian guards twenty-four hours a day and restricted by a nighttime curfew. In such a surveilled space, Venice’s ghetto windows played an integral role in the complex and interactive networks constituting the city and its constituency. The singular status of ghetto architecture—especially the injunctions regarding its fenestration—provides an opportunity to explore the processes of ghettoization that partitioned a population and monitored the activities of Jews and Christians alike. Windows produced spatial occasions for looking and being looked at that reinforced social difference and created profound cultural fissures. This article studies the windows of the Venetian ghetto and the city’s ongoing claims to obstruct them in the early modern period. To study the window is to study the demarcation between public good and private plurality, between the citizen and the subordinated Other.
