The corridor illusion

Contrary to general belief, the classical corridor illusion is not due solely to the perspective and contextual cues provided by the corridor. Additional factors that are equally important are the inherent spatial anisotropies of the visual system and fixation tendencies.     

Does Gender Nonconforming Behavior in Early Childhood Predict Adolescents’ Depressive Symptoms?

Sex Roles - Gender nonconforming behavior (GNB) is a risk factor for poorer psychological adjustment, but little is known about whether preschool-age children displaying GNB are at risk for...     

A Social Learning Perspective on Childhood Trauma and Same‐Sex Intimate Partner Violence

The family violence and childhood trauma literature has suggested that early adverse experiences create risk factors for intimate partner violence (IPV). Thus, this study used a sample of lesbian, gay, and bisexual (LGB) college students (N = 266) to explore differences among childhood trauma, same‐sex IPV, and IPV acceptance. The authors used survey methodology and multivariate analysis of variance. Results indicated that LGB individuals reporting childhood trauma also reported higher rates of IPV, suggesting implications for research and practice.     

The representation of social issues in public discourse and newspaper language: a comment on Gardikiotis,Martin and Hewstone's (2004) study

Gardikiotis, Martin and Hewstone ( 2004 ) investigated the representation of majority versus minority headlines in five British newspapers over a period of five years. They found majority headlines to be twice as frequent as minority headlines. However, they identified headlines with the search words ‘majority’ and ‘minority’ only in the singular form. We argue that in the public discourse the minority, but not the majority is likely to be represented in the plural. Replicating their study with the search words in both singular and plural forms, the strong difference they reported disappeared and minority headlines proved to be just as frequent as majority headlines. However, whereas majority is used almost exclusively in the singular, minority is used almost as frequently in both the singular and plural forms. These findings suggest a more complex social representation in real‐life contexts on the minority pole of the minority‐majority dimension compared to the majority pole. Implications of this asymmetric relationship are discussed in terms of communication theory, social representations theory, and experimental research on minority‐majority groups (in particular in‐group homogeneity).

On the theoretical error bound for estimating psychometric functions

The theoretical limits to the amount of error, or the Cramer-Rao bounds, were derived for estimating psychometric functions. These theoretical error bounds were compared with the variability of psychometric functions estimated from human as well as computer-simulated observers. For the simulated observers, due to the limited efficiency of the sampling strategies, including the placement of the signals and the distribution of the trials, the variances of the estimated parameters are seven times the theoretical bound for threshold and 22 times that for slope. For the human observers, the variance is 18 times the theoretical bounds for threshold and 80 times that for slope. Therefore, a major portion of the variances (60% for threshold and 73% for slope) for the human observers is associated with factors other than sampling strategies. Further improvement of the accuracy for estimating psychometric functions will depend on not only optimizing the sampling strategy, but also better understanding the various sources of error related to the behavior of human observers.     

Response latency as an index of response strength during functional analyses of problem behavior

Dependent variables in research on problem behavior typically are based on measures of response repetition, but these measures may be problematic when behavior poses high risk or when its occurrence terminates a session. We examined response latency as the index of behavior during assessment. In Experiment 1, we compared response rate and latency to the first response under acquisition and maintenance conditions. In Experiment 2, we compared data from existing functional analyses when graphed as rate versus latency. In Experiment 3, we compared results from pairs of independent functional analyses. Sessions in the first analysis were terminated following the first occurrence of behavior, whereas sessions in the second analysis lasted for 10 min. Results of all three studies showed an inverse relation between rate and latency, indicating that latency might be a useful measure of responding when repeated occurrences of behavior are undesirable or impractical to arrange.     

Ethnocentrism and Sexism: How Stereotypes Legitimize Six Types of Power

We review evidence of inequality associated with gender and social categories like ethnicity with respect to six types of power: control of resources, force, legitimacy, obligations, knowledge, and sexuality. Presuming that stereotypes are one means of legitimizing power differentials between groups, we review research on stereotype contents for both ethnicity and gender with respect to the six forms of power. The review reveals a number of rhetorical means by which stereotypes legitimize ethnic dominants and men having particular forms of power, such as disguising the exercise of power by describing it in individualistic rather than relational terms, and also how stereotypes de‐legitimize women and ethnic subordinates from obtaining particular forms of power, such as by stating that what they desire and their virtues preclude exercising power. A new research agenda regarding stereotypes and how they legitimize group power differences is outlined.
