Modality-Dependent and -Independent Factors in the Organisation of the Signed Language Lexicon: Insights From Semantic and Phonological Fluency Tasks in BSL

We used fluency tasks to investigate lexical organisation in Deaf adults who use British sign language (BSL). The number of responses produced to semantic categories did not differ from reports in spoken languages. However, there was considerable variability in the number of responses across phonological categories, and some signers had difficulty retrieving items. Responses were richly clustered according to semantic and/or phonological properties. With respect to phonology, there was significantly more clustering around the parameters “handshape” and “location” compared to “movement”. We conclude that the BSL lexicon is organised in similar ways to the lexicons of spoken languages, but that lexical retrieval is characterised by strong links between semantics and phonology; movement is less readily retrieved than handshape and location; and phonological fluency is difficult for signers because they have little metaphonological awareness in BSL and because signs do not display the onset salience that characterises spoken words.     

Intuitive (in)coherence judgments are guided by processing fluency, mood and affect

Recently proposed accounts of intuitive judgments of semantic coherence assume that processing fluency results in a positive affective response leading to successful assessment of semantic coherence. The present paper investigates whether processing fluency may indicate semantic incoherence as well. In two studies, we employ a new paradigm in which participants have to detect an incoherent item among semantically coherent words. In Study 1, we show participants accurately indicating an incoherent item despite not being able to provide an accurate solution to coherent words. Further, this effect is modified by affective valence of solution words that are not retrieved from memory. Study 2 replicates those results and extend them by showing that mood moderates incoherence judgments independently of affective valence of solutions. The results support processing fluency account of intuitive semantic coherence judgments and show that it is not fluency per se but fluency variations that drive judgments.     

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.     

How We Feel is a Matter of Time: Relationships Between Time Perspectives and Mood

Both personality and emotional experiences may be influenced by people’s time perspectives. The Zimbardo time perspective inventory measures five trait dimensions related to past, present and future perspectives. Two studies were conducted to investigate how these time perspective dimensions related to mood. The first study (n = 260) confirmed that ZTPI scales predicted moods including energetic arousal, tense arousal and Hedonic Tone, revealing that past negative and Present Hedonistic time perspectives are the most robust predictors of current emotional states. Moreover, future time perspective proved to predict energetic arousal, but the effect was suppressed by present hedonism. The second study (n = 65) measured mood twice in a 4-week period, and focused on relationships between the ZTPI and recalled and anticipated mood. Analyses conducted using DBTP, an index of temporal harmony based on the ZTPI scores, proved that balanced time perspective was related to more positive mood states in both studies. Findings confirmed that time perspective appears to influence both recall and anticipation of mood. For example, past negative time perspective is associated with anticipation of negative moods, and Past Positive perspective relates to both recall and anticipation of energy. Time perspective may structure the individual’s affective experience.     

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.     

Evaluating the Face Validity of the ICECAP-O Capabilities Measure: A “Think Aloud” Study with Hip and Knee Arthroplasty Patients

The ICECAP-O index of capabilities measure for older people is intended to be used in the evaluation of health and social care interventions. Focusing on quality of life, rather than health or other influences on quality of life. This study evaluated the face validity of the self-administered ICECAP-O capabilities measure for older people by investigating how participants interpret and respond to questions using the cognitive interviewing technique. Twenty patients with osteoarthritis of the knee or hip participated in a cognitive interview whilst completing the ICECAP-O capabilities measure. Cognitive interviews were conducted using the concurrent ‘think aloud’ design. All interviews were audio recorded and transcribed verbatim and analysed (i) using a standardised classification scheme to identify response problems and (ii) qualitatively thematically analysed to explore the nature of the problems that the participants experienced when completing the measure. Problems were identified in 7 % of participants’ responses. The majority of problems identified were comprehension problems. Thematic analysis highlighted the extent to which participants’ distinguished between functioning and capability. Cognitive interviewing was a valuable technique for pre-testing the face validity, acceptability and content validity of the ICECAP-O capabilities measure. Participants had minimal difficulties completing the ICECAP-O capabilities measure. Those difficulties identified have prompted suggestions for improving the measure.     

Improving Treatment Plan Implementation in Schools: A Meta-analysis of Single Subject Design Studies

Twenty-nine peer-reviewed journal articles that analyzed intervention implementation in schools using single-case experimental designs were meta-analyzed. These studies reported 171 separate data paths and provided 3,991 data points. The meta-analysis was accomplished by fitting data extracted from graphs in mixed linear growth models. This analytic approach was adopted to provide a model whose assumptions were met and could model both level and trend. The extent to which interventions were implemented as planned in baseline was low with a downward trend. Performance feedback, performance feedback augmented with additional procedures, and self-monitoring with environmental supports were found to be highly effective for improving intervention implementation. Follow-up meetings without review of implementation data were ineffective. Maintenance data were positive across studies. Implications of the results for future research and practice are discussed.     

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.
