Who is dominating the Dutch neighbourhood? On the role of subsyllabic units in Dutch nonword reading

To assess the role of the subsyllabic units onset–nucleus (ON; spa rk) and rime (sp ark ) in Dutch visual word recognition, we compared lexical decisions to four groups of nonwords in which the existence of ONs and rimes was orthogonally manipulated. Nonwords with existent ONs and/or rimes were rejected more slowly and less accurately. ON and rime neighbours thus influence Dutch nonword reading to the same extent. Simulations with the interactive activation model (McClelland & Rumelhart, 1981) revealed that this model with left-to-right coded representations could not replicate the effects found in the lexical decision data whereas an adapted version with representations of onset, nucleus, and coda could. Effects of the larger units ON and rime emerged from activation patterns created by the smaller units onset, nucleus, and coda.     

Use of Anticipatory Cues to Reduce Dependence on Physical Prompts by an Adolescent with Multiple Disabilities

Anticipatory cues (vibratory stimulation activated through remote control) were used in this study to help an adolescent with multiple disabilities to reduce his dependence on the caregiver's physical prompts. The results show that anticipatory cues were effective in helping the adolescent perform practical daily responses independently of physical prompts. Towards the end of the study, the adolescent could also perform increasingly independently of the anticipatory cues. Implications of the findings are discussed.     

Comparisons of Different Measures for Cognitions in Agoraphobic Patients

According to the cognitive models of panic disorder with and without agoraphobia, patients engage in catastrophic cognitions when anxious. An important question to address is the relationship between measures used in previous research. The present study compares different measures of cognitive material from the same sample of 70 patients with panic disorder with agrophobia. Cognitions were assessed through questionnaires, interview and self-monitoring during a behavioural avoidance test. No congruence between the different measures of cognitive material was found. Furthermore, cognitions collected through interview were more in line with the assumptions derived from the cognitive model, than were cognitions reported through self-monitoring. To answer the question whether this is due to methodological inadequacy or whether it reflects the state of affairs requires future research.     

Pre-adoptive risk factors and behavioural problems in children adopted from Poland

Behavioural problems in adoptees have been related to adverse circumstances prior to adoption. We examined pre-adoptive risk factors and post-adoptive behavioural problems in children adopted from Poland. Dutch adoptive parents of 133 Polish adoptees (M_age = 8.7 years, range 2.8–15.2; M_ageadoption = 3.0 years, range .4–6.9) answered the Child Behaviour Checklist and questions regarding pre-adoptive risk factors, such as institutionalization, neglect and abuse. Polish adoptees in our sample were four times more likely to have clinical behavioural problems than non-adopted children. Compared with a group of children adopted from various countries, predominantly from Asia, Polish adoptees had higher levels of behavioural problems as well. Multiple pre-adoptive risk factors were present. Only a history of abuse was found to be associated with behavioural problems after adoption. Special attention and support after adoption are needed for these children and their adoptive parents, especially when a pre-adoptive history of abuse is known.     

The impact of COVID-19 concerns on perceiving others' faces

Unlike most infectious diseases, COVID-19 is characterised by an absence of facial disease-signalling cues. Yet, it is still unclear whether it has influenced face perception. Understanding this may help clarify if and how our motivation toward social interactions is conditional on situational pathogen threats. The present study investigated if priming disease concerns about COVID-19 would change people's perception of neutral faces on perceived disease, social discomfort and arousal elicited by such faces; this condition was compared with other infectious/non-infectious diseases and a non-disease priming condition. One-hundred sixty-six participants recruited nationally performed the online task. When compared with the non-disease condition, participants primed for COVID-19 perceived faces as sicker and tended to view them as eliciting more social discomfort; no difference occurred in arousal. No other difference was found between conditions. These findings suggest that the pandemic context can shape how we perceive others' apparent sickness. Overall, these might reflect adaptations intertwined with the behavioural immune system's defence mechanisms.     

Electrical properties of thin films of a-Ga x Te100− x composed of nanoparticles

Thin films of Ga _x Te_{100? x} (x?=?3, 6, 9 and 12) have been synthesized by thermal evaporation. From SEM images, it is observed that all the films contain nanoparticles of sizes varying from 100 to 200?nm. The dc electrical conductivity of the as-deposited films of Ga _x Te_100?x nanoparticles is measured as a function of temperature range from 298 to 383?K, and increases exponentially with temperature. The value of the activation energy, calculated from the slope of ln?σ _dc versus 1000/T plots, is found to decrease with increase in the Ga content. On the basis of the value of the pre-exponential factor σ _o, it is suggested that the conduction is due to thermally assisted tunneling of carriers in localized states near the band edges. The optical measurements suggest an indirect optical band gap in this system. The value of the optical band gap decreases on increasing the Ga concentration.     

Dielectric relaxation in ternary systems of alcohols and nitriles in benzene at microwave frequency

The permittivity and the dielectric loss of ternary mixtures of equimolar concentrations of m-cresol, o-cresol with acetonitrile, acrylonitrile and benzonitrile in benzene have been measured at 8.33 GHz and 308 K. The distribution parameter α, the most probable relaxation time τ, the relaxation time for overall rotation of the molecule τ(1), the relaxation time for group rotation τ(2), and the excess dipole moment for various systems have been calculated by the Cole-Cole and Higasi methods. Data has been analyzed in terms of two-relaxation processes: overall rotation and group rotation.     

Recall of word lists is enhanced with increased spreading activation

ABSTRACT

Some evidence exists supporting a relationship between spreading activation in semantic/lexical memory networks and episodic memory. However, the results have been mixed and there have been no investigations examining whether a relationship exists between variability in spreading activation and episodic memory. Hence, we sought to investigate these potential relationships. Thirteen individuals were administered the Hopkins Verbal Learning Test–Revised (HVLT-R) and the Controlled Oral Word Association Test (COWAT). The average word frequency of all the “F” words generated on the COWAT was used as a measure of spreading activation. Variability in spreading activation was assessed by calculating the variability of the word frequencies from the COWAT across time. The results confirmed our hypotheses, with significant negative correlations found between free recall on the HVLT-R and both the average word frequency and measures of variability in spreading activation.     

An Examination of the Value of the Generation Effect for Learning New Material

The generation effect involves an improvement in memory when learners must complete or modify materials. Several researchers have suggested that this effect involves enhanced access to learners' existing memory representations; therefore, the effect should be less effective with meaningless, low meaningful, or unfamiliar material. In the present study, the authors conducted 4 experiments in which legal nonwords were used, and they found no generation effect. In another 2 experiments in which familiar clichés were contrasted with new sentences and with unfamiliar sentences from textbooks, the results showed a greatly reduced generation effect for the new, unfamiliar material. Those findings suggest that memory strategies that depend on the generation effect will have limited effectiveness when they are applied to new or unfamiliar material.
