Measuring the activity of severely and profoundly mentally-handicapped adults in ordinary housing

Earlier work on the quality of care in settings for severely and profoundly mentally-handicapped adults raised the question whether any useful purpose is served by promoting the extensive use of simple recreational materials to occupy people. Data were collected by direct observation on the activity of 6 adults living in a staffed house organized to promote engagement in household activities. Observations were taken over 5 weekdays from 07.00 to 10.00 and 15.00 to 23.00hr. The results showed that Ss spent between 22 and 67% of available time in purposeful activity. Between 27 and 65% of purposeful activity was engagement in domestic or housework tasks. Even the most handicapped people spent more time engaged in housework than in leisure and recreational tasks. The implications of these data are commented on and measurement issues which arise in ordinary housing as opposed to institutional settings are discussed.     

Development of comprehension of sentences with “because” or “if”

The comprehension of sentences with “because” or “if” was investigated in children aged 2;9–11;11. Imitation, comprehension (choosing one of two picture sequences to go with a sentence), recognition (judging sentences with connective or structure differences as heard before or not), and synonymy (judging equivalence of meaning in sentences with different connectives or structures) tasks were administered, along with logical ordering, reversibility, and classification tasks. Above-chance responding in the comprehension task occurred by age 8, and in recognition and synonymy by age 10. Cognitive performance predicted 28.4% of the variance in the linguistic scores and cognitive success was concurrent with or preceded linguistic success. Comprehension of “because” and “if” appears to develop gradually, and is related to the development of certain operative rules.     

Professional Counseling in Nigeria: Past,Present, and Future

The events that circumscribed the parameters of today's counseling in Nigeria are many and varied regarding their influence in shaping the development of the profession in the country. The authors review these events and the current status of counseling in Nigeria, including the challenges faced in the profession. Future trends and suggestions for strengthening the profession are emphasized.     

Acting with Feeling from Duty

A central claim in Kantian ethics is that an agent is properly morally motivated just in case she acts from duty alone. Bernard Williams, Michael Stocker, and Justin Oakley claim that certain emotionally infused actions, such as lending a compassionate helping hand, can only be done from compassion and not from duty. I argue that these critics have overlooked a distinction between an action's manner, how an action is done, and its motive, the agent's reason for acting. Through a range of examples I demonstrate how an emotion can determine an action's manner without also serving as the motive. Thus, it is possible for an agent to act compassionately from duty alone. This distinction between the manner and the motive of an action not only restores a central claim in Kantian ethics but it also allows for an expanded role of emotions in moral action.     

Present Bias and Everyday Self‐Control Failures: A Day Reconstruction Study

Everyday life is full of self‐control problems. The economist's favorite explanation for self‐control problems is present bias. This paper tests whether experimentally elicited present bias predicts self‐control problems in everyday life. We measure present bias by using a standard incentivized delay discounting task and everyday self‐control by using the day reconstruction method (DRM). Because this is the first study to measure everyday self‐control by using the DRM, we also validate the method by showing that its data replicate key results from the seminal Everyday Temptation Study. We find that present bias does not predict everyday self‐control. This points to a distinction between decreasing impatience (as measured in delay discounting tasks) and visceral influences (as occurring in everyday life) as determinants of self‐control problems. We argue that decision making research can benefit from the DRM as a cost‐effective tool that complements lab and field experiments to better understand economic preference measures and their correlates in everyday life decision making.

Perceiving the Present: Systematization of Illusions or Illusion of Systematization?

Mark Changizi et al. (2008) claim that it is possible systematically to organize more than 50 kinds of illusions in a 7 × 4 matrix of 28 classes. This systematization, they further maintain, can be explained by the operation of a single visual processing latency correction mechanism that they call “perceiving the present” (PTP). This brief report raises some concerns about the way a number of illusions are classified by the proposed systematization. It also poses two general problems—one empirical and one conceptual—for the PTP approach.     

Perceiving the present and a systematization of illusions

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called "perceiving the present," that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity.     

How to, and how not to, bridge computational cognitive neuroscience and Husserlian phenomenology of time consciousness

A number of recent attempts to bridge Husserlian phenomenology of time consciousness and contemporary tools and results from cognitive science or computational neuroscience are described and critiqued. An alternate proposal is outlined that lacks the weaknesses of existing accounts.
