We taught manual signs to typically developing infants using a reversal design and caregiver-nominated stimuli. We delivered the stimuli on a time-based schedule during baseline. During the intervention, we used progressive prompting and reinforcement, described by Thompson et al. (2004, 2007), to establish mands. Following sign training, we conducted functional analyses and verified that the s...

It has been documented that adolescent mothers are less verbally and emotionally responsive in their interactions with their children compared to adult mothers. These less than optimal adolescent mother/infant interactions have been found to affect the child's healthy growth and development. This small study aimed to identify and characterize the frequency of verbal behaviors exhibited in the i...

OBJECTIVE High-performance marine craft personnel (HPMCP) are regularly exposed to vibration and repeated shock (VRS) levels exceeding maximum limitations stated by international legislation. Whereas such exposure reportedly is detrimental to health and performance, the epidemiological data necessary to link these adverse effects causally to VRS are not available in the scientific literature, a...

We evaluated left and right motor cortex involvement during verbal and non-verbal lip and tongue movements in seven healthy subjects using whole-head magnetoencephalography. The movements were paced by tone pips. The non-verbal tasks included a kissing movement and touching the teeth with the tongue. The verbal tasks comprised silent articulation of the Finnish vowel /o/, which requires mouth m...

The association of verbal labels with visuo-spatial patterns and sequences detectably alters neuronal activity in the brain in ways that have yet to be fully characterized. This study investigated the neural substrates involved in the effect of spontaneous verbal labeling on memorizing increasingly complex sequences of hand movements. We used functional magnetic resonance imaging (fMRI) to test...

Do self-monitoring accounts, a dominant account of the positive symptoms of schizophrenia, explain auditory verbal hallucination? In this essay, I argue that the account fails to answer crucial questions any explanation of auditory verbal hallucination must address. Where the account provides a plausible answer, I make the case for an alternative explanation: auditory verbal hallucination is no...

The idea that verbal and non-verbal forms of memory are segregated in their entirety, and localized to the left and right hippocampi, is arguably the most influential concept in the neuropsychology of temporal lobe epilepsy, forming a cornerstone of pre-surgical decision making, and a frame for interpreting postoperative outcome. This critical review begins by examining some of the unexpressed ...

We explored the relationship between interactants’ social anxiety and the interactional fidelity of virtual humans. We specifically addressed whether the contingent non-verbal feedback of virtual humans affects the association between interactants’ social anxiety and their verbal self-disclosure. This subject was investigated across three experimental conditions where participants interacted wi...

background: regular physical activity is ranked as a leading health indicator. despite the extensive benefits of physical activity, elder people are much less active than desired. using theory of planned behavior (tpb) and the self-efficacy construct, this study examined the prediction of physical activity intention and behavior in a sample of elderly male resident of a nursing home. methods: i...
