Cognitive and Personality Characteristics of Masculinity and Femininity Predict Wayfinding Competence and Strategies of Men and Women

Bem (1974) reconceptualized masculinity and femininity as independent and orthogonal constructs that both men and women possess to varying degrees. This perspective was used as a starting point to investigate whether the contributions of gender-typed characteristics can help to account for commonly observed gender differences in wayfinding (the ability to identify one’s current location and successfully navigate to an unseen location in the environment) favoring men. We further divided gender-typed characteristics into cognitive and personality characteristics to assess their separate influence on wayfinding and explored whether gender-typed characteristics predicted self-reported use of masculine wayfinding strategies (i.e., orientation strategies) and self-reported wayfinding competence. Participants were 452 college women and men in a southern U.S. public university. They completed the Gender-Stereotypic Characteristics questionnaire (Diekman and Eagly 2000), a social comparison questionnaire (created by the authors), a wayfinding strategy questionnaire (Lawton 1994), and a wayfinding competence questionnaire (Hegarty et al. 2002). For both men and women, higher masculine cognitive characteristics significantly correlated with greater use of orientation wayfinding strategies typical of men. For men, both higher masculine and feminine cognitive characteristics predicted better overall wayfinding competence whereas for women, only higher masculine cognitive characteristics predicted better overall wayfinding competence. For both men and women, higher feminine personality characteristics predicted poorer wayfinding competence. These results demonstrated the importance of considering cognitive and personality characteristics of masculinity and femininity in explaining individual differences in wayfinding.     

Selection and consolidation of objects and actions

Response selection bottleneck models attribute performance costs under dual-task conditions to the human inability to select more than one response at a time. Consistent with this claim Pashler (1991) found that carrying out a speeded manual choice reaction time (RT) task does not impair the unspeeded report of a cued visual target from a masked display. In contrast, Jolicoeur and DellAcqua (1999, Experiment 2) observed pronounced interference between a speeded manual choice RT task and the unspeeded report of a small number of visually presented letters, a finding they attributed to resource sharing between response selection and stimulus consolidation. We demonstrate that comparable costs are obtained with the same task combination used by Pashler (1991) if only task order is reversed—a manipulation that is likely to increase the necessity of consolidating the target stimulus into working memory. We also found that these costs are not diminished if the location of the target to be reported is cued in advance (reducing demands on spatial focusing) and that they do not vary with the number of target features to be reported. These findings support a consolidation account of costs in dual-task performance.     

Causal and Moral Responsibility of Victims of Rape and Robbery

Four experimental studies of attribution in a criminal situation used a 2⁴ ANOVA design with three common independent variables, namely, type of crime, time of crime, and victim's prior experience of crime, all three manipulated through a passage describing an incident of crime involving a male criminal and a female victim, and one common dependent measure which was length of imprisonment recommended for the criminal. The fourth independent variable was subject's sex in the first two experiments and instructionally manipulated female subject's involvement (objective or identifying female subject) in the last two experiments. The second dependent measure was fault attributed to the victim in the first and third experiments and perceived likelihood of crime in the second and fourth experiments. The subjects were undergraduate students of the University of Bombay, 15 per cell in each experiment. Female subjects were more punitive toward the criminal than male subjects, especially in the case of rape, and the rapist received a longer sentence than the robber, especially from female subjects. Identifying female subjects tended to recommend a longer sentence than objective female subjects. Female subjects attributed less fault to the victim and perceived greater likelihood of crime than male subjects and identifying female subjects attributed somewhat less fault to the victim than did objective female subjects. The robbery victim was attributed more fault than the rape victim. Whereas previous experience of similar victimization increased attributed victim's fault, a late hour enhanced both attributed victim's fault and perceived likelihood of crime. These findings are discussed with respect to a theoretical distinction between causal and moral responsibility as represented by the likellhood and fault measures, respectively.     

Effects of norms and norm-violations on inhibition and instigation of aggression

It was hypothesized that in a competitive interaction in which an opponent first used threats and fines a) subjects would use the highest level of coercion that could be justified by the available norms, b) subjects would be inhibited by a norm that justified using only low levels of coercion, but c) when the opponent used a magnitude of coercion which exceeded the norm, subjects would also violate the norm and retaliate with an equally high magnitude of coercion, and d) subjects would use the maximum levels of coercion when engaging in a competitive game without norms. These hypotheses were examined in a 3 × 2 factorial experiment in which the amount of coercion allowable by a norm (Low Norm, High Norm, and No Information) and the level of coercion (Low or High) were manipulated. As predicted, aggressive reactions by subjects were inhibited when the provoker conformed to a low norm by using a low level of coercion. On the other hand, subjects retaliated by using a high level of coercion when the level of coercion used by a provoker violated the norm. Subjects who could justify their behavior by the availability of a high punitive norm tended to use all of the coercive power available to them even when the provoker used a low level of coercion. © 1996 Wiley-Liss, Inc.     

Models of Trajectory Formation and Temporal Interaction of Reach and Grasp

Our goal was to create a principled account of a body of behavioral kinematic data on reaching and grasping. We show how to transform an optimality principle for overall hand transport into a feedback control law and then incorporate look-ahead modules in the controller to compensate for delays in sensory feedback. This model describes the kinematics of hand transport under a variety of circumstances, including target perturbations. We then develop a model for the temporal coordination of reach and grasp. We provide an optimization principle for hand preshaping that trades off the costs of maintaining the hand in an open position and the cost of accelerating the change in grip size. This yields a control system for preshaping. We then show that a model that uses only expected duration for coordination, rather than kinematic or dynamic variables, can describe the kinematics of interaction of hand transport and preshape under a variety of circumstances, including perturbations of object position and object size.     

Inhibition and decay of motor and nonmotor priming

Motor responses can be facilitated by congruent visual stimuli and prolonged by incongruent visual stimuli that are made invisible by masking (direct motor priming). Recent studies on direct motor priming showed a reversal of these priming effects when a three-stimulus paradigm was used in which a prime was followed by a mask and a target stimulus was presented after a delay. A similar three-stimulus paradigm on nonmotor priming, however, showed no reversal of priming effects when the mask was used as a cue for processing of the following target stimulus (cue priming). Experiment 1 showed that the time interval between mask and target is crucial for the reversal of priming. Therefore, the time interval between mask and target was varied in three experiments to see whether cue priming is also subject to inhibition at a certain time interval. Cues indicated (1) the stimulus modality of the target stimulus, (2) the task to be performed on a multidimensional auditory stimulus, or (3) part of the motor response. Whereas direct motor priming showed the reversal of priming about 100 msec after mask presentation, cue priming effects simply decayed during the 300 msec after mask presentation. These findings provide boundary conditions for accounts of inverse priming effects.     

Evaluating competence of women and men: Effects of marital and parental status and occupational sex-typing

A sample of 160 female and male college students read a completed job application and a letter written by the applicant. The job was in either a feminine or a masculine field. The applicant was described as either female or male, single or married, and having one or no children. Subjects answered seven evaluative questions about the competence of the applicant and the merits of the letter. Women, especially single ones, who applied for a sex-typical job generally were evaluated most favorably. Men, especially single ones, and women who applied for sex-atypical jobs were evaluated least favorably.     

Cybersemiotics and the Question of Semiotic and Informational Thresholds

The present article discusses various suggestions for a philosophical framework for a transdisciplinary information science or a semiotic doctrine. These are: the mechanical materialistic, the pan-informational, the Luhmanian second order cybernetic approach, Peircian biosemiotics and finally the pan-semiotic approach. The limitations of each are analyzed. The conclusion is that we will not have to choose between either a cybernetic-informational or a semiotic approach. A combination of a Peircian-based biosemiotics with autopoiesis theory, second order cybernetics and information science is suggested in a five-leveled cybersemiotic framework. The five levels are 1) a level of Firstness, 2) a level of mechanical matter, energy and force as Secondness, 3) a cybernetic and thermodynamic level of information and signal, 4) a level of sign games in living systems, and 5) a level of conscious language games in self-conscious social humans.     

Causality and the categorisation of objects and events

The “Tower of London” puzzle was adapted to tablet PCs to be used as a clinical bedside test. “Iso-problems”, a specific class of problems, require identical moves but ball colours are permuted. Thus difficulty is the same even if the appearance is different. We wanted to determine the impact of these as yet little-studied tasks and hypothesised that there may be a learning effect specific to them (the “iso-effect”). We interspersed a set of six iso-problems within one selection of 22 tasks and analysed problem solving by 81 healthy adults (mean age 41.6 years). Participants showed learning across iso-problems (less time, fewer moves, increasingly efficient solutions). This effect was distinct from general learning, as was obvious from comparison with a series of non-isomorphic tasks. However, participants seem not to be aware of solving such problems. This “iso-effect” may be related to implicit memory, a domain that so far has not been assessed using the Tower of London.     

Impact of Ethnicity and Sex on Personal Values and Socialization Experiences of Canadian Anglophones and Francophones

This study of Canadian male and female undergraduates (88 Anglophones and 78 Francophones of matched socioeconomic status) yielded value structure data of high overall similarity across ethnolinguistic group membership and sex. Both groups ranked wisdom, a sense of accomplishment, a world of peace and beauty as most important, and a pleasant life, freedom, salvation, and social recognition as least important to them. Males placed more emphasis on a pleasant exciting life and being broadminded, while females emphasized inner harmony. Differential socialization experiences across ethnolinguistic group membership were religion, family size, parental influence on choice of studies, and parental discipline. Family closeness and patriarchal power structure were differentially perceived across sex. In general, results offered minimal support to a “two solitudes” concept in the human values area.     

Frequency of Exposure and Evaluation of Candidates and Campaign Speeches1

Three slides, each showing the photograph of a college-age male, were shown either 5, 10, or 25 times to a total of 95 students (S s). After the presentation, the slides, plus a fourth not previously shown, were presented as photographs of candidates in a campus election, each being paired with a campaign speech. Three speeches consisted of bland platitudes, whereas the fourth argued in favor of a large tuition increase. Ratings of the speeches and the candidates indicated that subjects were accurate in ranking the relative frequency of exposure of the four slides and that the controversial speech elicited less agreement and less favorable ratings than the three other messages. There were U-shaped curvilinear effects of exposure on S s' agreement with the messages, and with ratings of the persuasiveness of the message. Neither exposure nor speech effects were found in ratings of the candidates themselves. Implications of these findings for the frequency of exposure hypothesis (Zajonc, 1968) and for political campaigns are discussed.     

Enactivism and the Unity of Perception and Action

This paper contrasts two enactive theories of visual experience: the sensorimotor theory (O’Regan and Noë, Behav Brain Sci 24(5):939–1031, 2001; Noë and O’Regan, Vision and mind, 2002; Noë, Action in perception, 2004) and Susan Hurley’s (Consciousness in action, 1998, Synthese 129:3–40, 2001) theory of active perception. We criticise the sensorimotor theory for its commitment to a distinction between mere sensorimotor behaviour and cognition. This is a distinction that is firmly rejected by Hurley. Hurley argues that personal level cognitive abilities emerge out of a complex dynamic feedback system at the subpersonal level. Moreover reflection on the role of eye movements in visual perception establishes a further sense in which a distinction between sensorimotor behaviour and cognition cannot be sustained. The sensorimotor theory has recently come under critical fire (see e.g. Block, J Philos CII(5):259–272, 2005; Prinz, Psyche, 12(1):1–19, 2006; Aizawa, J Philos CIV(1), 2007) for mistaking a merely causal contribution of action to perception for a constitutive contribution. We further argue that the sensorimotor theory is particularly vulnerable to this objection in a way that Hurley’s active perception theory is not. This presents an additional reason for preferring Hurley’s theory as providing a conceptual framework for the enactive programme.     

Counselling and the dislocation of representation and reality

Counselling theories have typically assumed a nomenclaturist view of language. This has been subject to increasing criticism in this century. Two alternative views of language and reality to nomenclaturism are discussed as a basis for post-modern therapeutic practice. It is argued that a post-modem view of counselling should recognise both the value and limitations of language, and in doing so should recognise the value and limitations of counselling as a means of therapy.     

Parameters of visual simultaneity and of metacontrast and paracontrast of successively presented letters

Two stimuli of three consonants each were successively presented through a tachistoscope. Results show that the shorter the totr 1 duration of S₁, + ISI + S₂, the more often the two stimuli are perceived as simultaneous. For a given total duration, the perception of simultaneity depends on the ratio of durations S₁/S₂, according to a nonmonotonic function. The optimum is reached for a ratio higher than one. When the S₁/S₂ ratio increases from 0.25 to 4, metacontrast decreases and paracontrast increases. These two phenomena are balanced for a value of the S₁/S₂ ratio which corresponds to the optimum of the perception of simultaneity.     

Perception and masking of wholes and parts

These exerpiments show that the effects of masking on reports of target lines depend on the context in which the target lines appear. Subjects viewed brief presentations of target lines either alone or in drawings of three-dimensional objects, and each target display was preceded and followed by one of several different mask stimuli. There were two main findings: (a) A mask containing a haphazard array of lines interfered more with single lines than it did with lines in objects. (b) A mask containing drawings of the object displays interfered more with lines in objects than did either of two control masks containing relatively flat, less coherent patterns. In a control condition, the object mask interfered slightly less with reports of single lines than either of the control masks did. The discussion considers how the effects obtained here bear on models of the processing of wholistic stimuli and their component parts.     

Focus of attention and causal attributions of actors and observers

An experiment was conducted to test the hypothesis that actors' and observers' causal attributions are a function of their focus of attention. In the presence of observer-subjects, actor-subjects made a choice among several art works in a supposed decision-making study. The experiment was a 2 × 2 × 2 factorial design with the factors (1) source of attribution (actors, observers); (2) camera (actor videotaped, actor not videotaped); and (3) situational stability (stable, dynamic environment). As predicted by the focus of attention-causal attribution notion, it was found that actors attributed more causality to the situation than observers under normal circumstances, when the camera was not operative, but that videotaping the actor reversed the usual actor-observer pattern such that actors attributed less causality to the situation than did observers. Further, when the environment was stable, actors attributed more causality to the situation in the no camera condition than in the camera condition, while observers attributed less to the situation in the no camera conditions than in the camera conditions. Additionally, both actors and observers attributed more causality to the situation when the environment was dynamic than when the environment was stable.     

Advantages and Disadvantages of Solar Energy and Wind-Power Utilization

Wind-mills were widely used for grinding corn in the last century in Hungary. The use of solar energy for water heating, taking a bath, shower, and drying crops has had a tradition for a long time. This article presents in what proportion the two types of energy are disposable in the course of the year, how this difference between the simultaneous disposability of the two types of sources of energy changes depending on seasons, and by what a diffusion and variance in a month, a part of a day, or an hour the examined parameters can be characterized.     

Film Analysis and Psychophysiology Effects of Moments of Impact and Protagonists

An interdisciplinary empirical approach that connects film analysis and psychophysiological measurement is used to investigate the effects of narrative structures and their combinations (moments of impact), and the effects of narrative structures associated with protagonists. The film The Piano by Jane Campion is employed in the assessment. The features of the film that are relevant for the reception process are determined on the basis of a film-analytic model. For 60 participants changes of heart rate as an indicator for attention processes were examined by adapting time-series strategies. An analysis of the individual processes demonstrates that narrative structures associated with protagonists cause significant reactions, whereas only few parameter estimations for reactions to moments of impact are significant. The parameter estimations differ to a high degree from person to person. The results of the analysis of the common process of all participants support the findings. The supported relevance of narrative structures perceived on a more subconscious level opens empirical access to a still unexplored level of media communication. Perspectives for future research using physiological measurement and time series analysis are discussed.
