Distance estimates of children as a function of acquisition and response activities

Second and sixth graders (8 and 12 years of age, respectively) experienced a large-scale environment either actively or passively followed by a distance estimation task requiring either active or passive activity. Second graders were most accurate in those conditions where acquisition and response activities were congruent. These children significantly overestimated distances in the passive acquisition-active response condition. Sixth graders were equally accurate across all four experimental conditions. Results are discussed in terms of the complex interaction between acquisition factors and task demands which influence interpretations about spatial representations.     

Responding in the cat maintained under response-independent electric shock and response-produced electric shock

Key-pressing responses in the cat were maintained under conditions in which brief electric shock was first postponed by responses (avoidance), then periodically presented independently of responses, and finally produced by responses on a fixed-interval schedule of 15 min (FI 15-min). A steady rate of responding occurred under shock avoidance and under response-independent shock; positively accelerated responding was engendered by the FI 15-min schedule. A second experiment studied responding under second-order schedules composed of three FI 5-min components. Responding was suppressed when a stimulus was presented briefly at completion of each FI 5-min component and a shock followed the brief stimulus at completion of the third component. Responding was maintained when each of the first two components was completed either with or without presentation of a brief stimulus and a shock alone was presented at completion of the third FI 5-min component.     

On the brightness of short and long flashes

The equation proposed by S. S. Stevens to describe the relations among brightness, intensity, and duration involves assumptions that are here made explicit. The equation is shown to apply to earlier studies designed to measure critical duration.     

SENSATIONS, SWATCHES, AND SPECKLED HENS

Abstract: We argue that there is a interesting connection between the old problem of the Speckled Hen and an argument that can be traced from Russell to Armstrong to Putnam that we call the “gradation argument.” Both arguments have been used to show that there is no “Highest Common Factor” between appearances we judge the same – no such thing as “real” sensations. But, we argue, both only impugn the assumption of epistemic certainty regarding introspective reports.     

Do People Really Have Insights in the Shower? The When,Where and Who of the Aha! Moment

While there are well‐known anecdotes and documented insight cases by renowned scientists and inventors, little is known about the experiences of insight in the general population. The present study aimed to determine peoples' self‐reported experience of insight in their daily lives. Using an online questionnaire, responses were obtained from 1,114 respondents. Eighty‐percent reported having insights. These respondents reported demographic information and answered three open‐ended questions on where their insights occur, what insights are and other thoughts on insight. A greater percentage of those who have insights are, female, younger, highly educated, and involved in occupations including, management, sciences, arts and service professions. The qualitative results uncovered eight major themes, reflecting on the places people have insights: At night, work, shower, home, when it is quiet, transport, while exercising, and in nature. Two major themes emerged on what insights are: Something from the subconscious, and a result of (not) thinking. Finally, three major themes emerged from the third question on thoughts they would like to share on insight: The improvement of insight with age, the importance of analyzing the details of the problem, and the unexpectedness of the solution. Results are discussed in the context of the current experimental research on insight.     

Slurs,roles and power

Slurring is a kind of hate speech that has various effects. Notable among these is variable offence. Slurs vary in offence across words, uses, and the reactions of audience members. Patterns of offence aren’t adequately explained by current theories. We propose an explanation based on the unjust power imbalance that a slur seeks to achieve. Our starting observation is that in discourse participants take on discourse roles. These are typically inherited from social roles, but only exist during a discourse. A slurring act is a speech-act that alters the discourse roles of the target and speaker. By assigning discourse roles the speaker unjustly changes the power balance in the dialogue. This has a variety of effects on the target and audience. We show how these notions explain all three types of offence variation. We also briefly sketch how a role and power theory can help explain silencing and appropriation. Explanatory power lies in the fact that offence is correlated with the perceived unjustness of the power imbalance created.
