The dynamics of search,impasse, and representational change provide a coherent explanation of difficulty in the nine-dot problem

The nine-dot problem is often used to demonstrate and explain mental impasse, creativity, and out of the box thinking. The present study investigated the interplay of a restricted initial search space, the likelihood of invoking a representational change, and the subsequent constraining of an unrestricted search space. In three experimental conditions, participants worked on different versions of the nine-dot problem that hinted at removing particular sources of difficulty from the standard problem. The hints were incremental such that the first suggested a possible route for a solution attempt; the second additionally indicated the dot at which lines meet on the solution path; and the final condition also provided non-dot locations that appear in the solution path. The results showed that in the experimental conditions, representational change is encountered more quickly and problems are solved more often than for the control group. We propose a cognitive model that focuses on general problem-solving heuristics and representational change to explain problem difficulty.     

Precursors to aggression are evident by 6 months of age

We tested the hypothesis that developmental precursors to aggression are apparent in infancy. Up to three informants rated 301 firstborn infants for early signs of anger, hitting and biting; 279 (93%) were assessed again as toddlers. Informants' ratings were validated by direct observation at both ages. The precursor behaviours were significantly associated with known risk factors for high levels of aggressiveness. Individual differences were stable from early infancy to the third year and predicted broader conduct problems. These findings suggest that some individuals set forth on the trajectory to high levels of aggression by 6 months of age. The findings have implications for developmental studies of aggression, clinical prevention and intervention strategies, and theoretical considerations regarding the detection of precursors in different domains of development.     

Dirty Money

Many states have significantly reduced their support for higher education in the last decade, increasing the importance of securing external funding for research and academic centers at colleges and universities. This paper addresses issues that have been raised by critics of funding from "morally tainted" sources like tobacco companies, pharmaceutical companies, and oil and gas companies and attempts to develop plausible criteria for "morally acceptable" funding in light of criticisms that focus on issues such as transparency, conflicts of interests, academic and scientific integrity, and coercion. A further discussion of whether special or unique criteria are necessary for ethicists and ethics centers is also included.     

The ethics of animal research: a survey of pediatric health care workers

Introduction

Pediatric health care workers (HCW) often perform, promote, and advocate use of public funds for animal research (AR). We aim to determine whether HCW consider common arguments (and counterarguments) in support (or not) of AR convincing.

Design

After development and validation, an e-mail survey was sent to all pediatricians and pediatric intensive care unit nurses and respiratory therapists (RTs) affiliated with a Canadian University. We presented questions about demographics, support for AR, and common arguments (with their counterarguments) to justify the moral permissibility (or not) of AR. Responses are reported using standard tabulations. Responses of pediatricians and nurses/RTs were compared using Chi-square, with P?<?.05 considered significant.

Results

Response rate was 53/115(46%) (pediatricians), and 73/120(61%) (nurses/RTs). Pediatricians and nurses/RTs are supportive of AR. Most considered ‘benefits arguments’ sufficient to justify AR; however, most acknowledged that counterarguments suggesting alternative research methods may be available, or that it is unclear why the same ‘benefits arguments’ do not apply to using humans in research, significantly weakened ‘benefits arguments’. Almost all were not convinced of the moral permissibility of AR by ‘characteristics of non-human-animals arguments’, including that non-human-animals may not be sentient, or are simply property. Most were not convinced of the moral permissibility of AR by ‘human exceptionalism’ arguments, including that humans have more advanced mental abilities, are of a special ‘kind’, can enter into social contracts, or face a ‘lifeboat situation’. Counterarguments explained much of this, including that not all humans have these more advanced abilities [the argument from species overlap], and that the notion of ‘kind’ is arbitrary [e.g., why are we not of the kind ‘sentient animal’ or ‘subject-of-a-life’]. Pediatrician and nurse/RT responses were similar.

Conclusions

Most respondents were not convinced of the moral permissibility of AR when given common arguments and counterarguments from the literature. HCW should seriously consider arguments on both sides of the AR debate.

     

Service and Medication Use and Their Effects on Arrest Rates Among Children with Emotional Disturbances Before Disenrollment from Medicaid

In this study we examine two assumptions that underlie the hypothesis that the outcomes of children with emotional disturbances are negatively affected by the loss of access to mental health services during their transitions to adulthood. The first is that children access mental health services during the pre-transition years, and the second is that these services are effective in reducing poor outcomes. We tested these assumptions using children who lost Medicaid enrollment between their 18th and 20th birthdays in Florida’s Medicaid program using arrests as the outcome. All children with an emotional disturbance received at least one outpatient service. However, while the mean days of service per month were 3, more than half the children received less than one day of service. Fifty-six percent of children received some psychotherapeutic medication treatment. Children with ADHD had the highest number of days of medication per month in both univariate and multivariate analysis. In multivariate analysis, children with disruptive behavior disorders had significantly more days per month of outpatient services than children with any other diagnoses except anxiety disorders. Medication days but not outpatient service days were negatively associated with arrests. Post hoc analysis suggested that children with ADHD who had high medication days had significantly fewer arrests than children with disruptive behavior disorders. This was not the case for children with ADHD and low medication days. Children with ADHD and high medication use may be most at risk of increases in arrests after Medicaid disenrollment as many will lose access to a service that was associated with fewer arrests. Findings suggest the need for reform of the children’s mental health system.     

TEACHING RESPONSES TO QUESTIONS TO YOUNG CHILDREN WITH DOWN SYNDROME

Despite extensive evidence of significant and pervasive impairments in communication in individuals with Down syndrome, there is relatively little empirical and behavior analytic research demonstrating effective intervention procedures. In this study, we examined a behavior analytic intervention to teach answers to questions in two children with Down syndrome. Children acquired the target responses and generalized across settings and people. This contributes to the growing body of demonstrations of behavior analytic interventions to address the needs of children with Down syndrome. Copyright © 2013 John Wiley & Sons, Ltd.     

The perception of a familiar face is no more than the sum of its parts

Why do faces become easier to recognize with repeated exposure? Previous research has suggested that familiarity may induce a qualitative shift in visual processing from an independent analysis of individual facial features to analysis that includes information about the relationships among features (Farah, Wilson, Drain, & Tanaka Psychological Review, 105, 482–498, 1998; Maurer, Grand, & Mondloch Trends in Cognitive Science, 6, 255–260, 2002). We tested this idea by using a “summation-at-threshold” technique (Gold, Mundy, & Tjan Psychological Science, 23, 427–434, 2012; Nandy & Tjan Journal of Vision, 8, 3.1–20, 2008), in which an observer’s ability to recognize each individual facial feature shown independently is used to predict their ability to recognize all of the features shown in combination. We find that, although people are better overall at recognizing familiar as opposed to unfamiliar faces, their ability to integrate information across features is similar for unfamiliar and highly familiar faces and is well predicted by their ability to recognize each of the facial features shown in isolation. These results are consistent with the idea that familiarity has a quantitative effect on the efficiency with which information is extracted from individual features, rather than a qualitative effect on the process by which features are combined.     

You learn it in your heart: transformative learning theory and clinical pastoral education

This article offers a broad overview of transformative learning theory focusing primarily on the rational and affective dimensions of the theory. As a comprehensive theory of adult learning, transformative learning theory seeks to articulate a process by which persons make meaning of their experiences and their lives. The theory provides a solid educational basis for the learning process in CPE. A list of major sources in the theory is included.     

A phenomenological survey of auditory verbal hallucinations in the hypnagogic and hypnopompic states

The phenomenology of auditory verbal hallucinations (AVHs) occurring in hypnagogic and hypnopompic (H&H) states has received little attention. In a sample of healthy participants (N = 325), 108 participants reported H&H AVHs and answered subsequent questions on their phenomenology. AVHs in the H&H state were found (1) to be more likely to only feature the occasional clear word than to be clear, (2) to be more likely to be one-off voices than to be recurrent voices, (3) to be more likely to be voices of people known to the individual than unknown persons, (4) to be more likely to talk directly to the person rather than not, and (5) to only rarely give commands, ask questions, or to result in an interactive conversation. Their phenomenology was similar to normative AVHs in wakefulness (as established by previous research) in that the voice-hearer was usually the target of the voice, and the voice was more likely to be of a recognized person. However, H&H AVHs differed from AVHs in wakefulness in that commands and questions were rare, and there was typically no dialogical engagement with the voice. We conclude by proposing that two distinct types of H&H AVHs may exist (which we term “dialogic” and “monologic”), based on an analysis of the phenomenology of the experience, and suggest avenues for future research.
