Adaptation of the Mullen Scales of Early Learning for use among infants aged 5‐ to 24‐months in rural Gambia

Infants in low‐resource settings are at heightened risk for compromised cognitive development due to a multitude of environmental insults in their surroundings. However, the onset of adverse outcomes and trajectory of cognitive development in these settings is not well understood. The aims of the present study were to adapt the Mullen Scales of Early Learning (MSEL) for use with infants in a rural area of The Gambia, to examine cognitive development in the first 24‐months of life and to assess the association between cognitive performance and physical growth. In Phase 1 of this study, the adapted MSEL was tested on 52 infants aged 9‐ to 24‐months (some of whom were tested longitudinally at two time points). Further optimization and training were undertaken and Phase 2 of the study was conducted, where the original measures were administered to 119 newly recruited infants aged 5‐ to 24‐months. Infant length, weight and head circumference were measured concurrently in both phases. Participants from both phases were split into age categories of 5–9 m (N = 32), 10–14 m (N = 92), 15–19 m (N = 53) and 20–24 m (N = 43) and performance was compared across age groups. From the ages of 10–14 m, Gambian infants obtained lower MSEL scores than US norms. Performance decreased with age and was lowest in the 20–24 m old group. Differential onsets of reduced performance were observed in the individual MSEL domains, with declines in visual perception and motor performance detected as early as at 10–14 months, while reduced language scores became evident after 15–19 months of age. Performance on the MSEL was significantly associated with measures of growth.     

Counteracting performativity in schools: the case for laughter as a qualitative and redemptive indicator

The auditing culture and its concomitant, ‘performativity’, have been at the core of the on‐going public sector reforms of the last twenty‐five years or so. The advantages and limitations of performance indicators as a managerial technique of control have long been known. Considered from an organisational, social and political perspective, it is now possible to evaluate the predictions made in the 1980s and 1990s. These focused on the consequences for the cultures of educational institutions and the emotional resilience of individuals – especially the children – within them, if techniques of this kind are inappropriately managed and emphasise the impersonal and quantitative. The article offers a compromise solution that balances effectiveness with humanity and spirituality, in the form of a radical performance indicator, namely, laughter.

Social anxiety in children: social skills deficit, or cognitive distortion?

BACKGROUND: Treatments for childhood social anxiety have traditionally employed social skills training, based on the assumption that effected children have social skills deficits. Recent conceptualisations of social anxiety in adults have questioned this assumption, and have suggested that socially anxious individuals merely believe that they have skill deficits. A recent study using children provided preliminary confirmation of this for younger populations, and also suggested that beliefs about appearing nervous are of particular importance. METHODS: Two groups of children, aged 10-11 years (analogue high social anxiety/low social anxiety), participated in a conversation with an unfamiliar adult. They then rated their performance in a number of domains, after which independent observers also rated their performances. RESULTS: Independent observers were unable to distinguish between the low and high social anxiety groups. However, high socially anxious children rated themselves as appearing significantly less skilled than their low socially anxious counterparts. Notably, high socially anxious children rated themselves particularly poorly in terms of how nervous they looked. CONCLUSIONS: Socially anxious children may not necessarily display social skill deficits. However, they may believe that they appear nervous during social encounters. Clinicians should consider using CBT techniques to address these concerns, rather than relying on social skill remediation.     

Modulation of brain activity during phonological familiarization

We measured brain activity in 12 adults for the repetition of auditorily presented words and nonwords, before and after repeated exposure to their phonological form. The nonword phoneme combinations were either of high (HF) or low (LF) phonotactic frequency. After familiarization, we observed, for both word and nonword conditions, decreased activation in the left posterior superior temporal gyrus, in the bilateral temporal pole and middle temporal gyri. At the same time, interaction analysis showed that the magnitude of decrease of activity in bilateral posterior temporal lobe was significantly smaller for LF nonwords, relative to words and HF nonwords. Decrease of activity in this area also correlated with the size of behavioral familiarization effects for LF nonwords. The results show that the posterior superior temporal gyrus plays a fundamental role during phonological learning. Its relationship to sublexical and lexical phonological processing as well as to phonological short-term memory is discussed.     

The neural correlates of implicit and explicit sequence learning: Interacting networks revealed by the process dissociation procedure

In two H2(15)O PET scan experiments, we investigated the cerebral correlates of explicit and implicit knowledge in a serial reaction time (SRT) task. To do so, we used a novel application of the Process Dissociation Procedure, a behavioral paradigm that makes it possible to separately assess conscious and unconscious contributions to performance during a subsequent sequence generation task. To manipulate the extent to which the repeating sequential pattern was learned explicitly, we varied the pace of the choice reaction time task-a variable that is known to have differential effects on the extent to which sensitivity to sequence structure involves implicit or explicit knowledge. Results showed that activity in the striatum subtends the implicit component of performance during recollection of a learned sequence, whereas the anterior cingulate/mesial prefrontal cortex (ACC/MPFC) supports the explicit component. Most importantly, we found that the ACC/MPFC exerts control on the activity of the striatum during retrieval of the sequence after explicit learning, whereas the activity of these regions is uncoupled when learning had been essentially implicit. These data suggest that implicit learning processes can be successfully controlled by conscious knowledge when learning is essentially explicit. They also supply further evidence for a partial dissociation between the neural substrates supporting conscious and nonconscious components of performance during recollection of a learned sequence.     

Building youths' resilience within a psychiatric outpatient setting: results from a pilot clinical intervention project

The relevance of resilience research for clinical practice has not yet been established. In this intervention pilot study, the aim was to explore how group work based on enhancing the participants' creativity, self-efficacy, active coping, and sense of continuity could be utilized within a clinical context for adolescents with stressful background experiences. 31 participants and 24 parents completed pre-, post-, and 1-yr. follow-up assessments of the youths' behavior difficulties, as well as depression, positive life attitude, coping, and prosocial behavior. Apart from a drop in self-rated prosocial behavior, no significant treatment effects were found. Implications for clinical practice and research are indicated.     

A positive emotional bias in confabulatory false beliefs about place

Some neurological patients with medial frontal lesions exhibit striking confabulations. Most accounts of the cause of confabulations are cognitive, though the literature has produced anecdotal suggestions that confabulations may not be emotionally neutral, having a ('wish-fulfilment') bias that shapes the patient's perception of reality in a more affectively positive direction. The present study reviewed every case (N = 16) of false beliefs about place reported in the neuroscientific literature from 1980 to 2000, with blind raters evaluating the 'pleasantness' of the patient's actual and confabulated locations. In each case the confabulated location was evaluated as more pleasant. This striking finding supports the claim that there may be a systematic affective bias in the false beliefs held by neurological patients with confabulation.     

Interactive effects of numerical surface form and operand parity in cognitive arithmetic

In Experiment 1, adults (n = 48) performed simple addition, multiplication, and parity (i.e., odd-even) comparisons on pairs of Arabic digits or English number words. For addition and comparison, but not multiplication, response time increased with the number of odd operands. For addition, but not comparison, this parity effect was greater for words than for digits. In Experiment 2, adults (n = 50) solved simple addition problems in digit and word format and reported their strategies (i.e., retrieval or procedures). Procedural strategies were used more for odd than even addends and much more for word than digit problems. The results indicate that problem encoding and answer retrieval processes for cognitive arithmetic are interactive rather than strictly additive stages.
