Introduction: Hearing loss occurs when there is a problem with one or more parts of the ear or ears and causes children to have a delay in the language-learning process. Hearing loss affects children's lives and their development. Several approaches have been developed over recent decades to help hearing-impaired children develop language skills. Auditory-verbal therapy (AVT) is one such approa...

Verbal episodic memory deficits, a well-established feature of the schizophrenia spectrum, have also been found in individuals with schizotypal personality disorder (SPD), although visual-spatial episodic memory has proven harder to examine. To address this, we administered the Visual Object Learning Test (VOLT), a measure of visual-spatial learning and memory, as well as the California Verbal ...

BACKGROUND One of the cardinal features of schizotypal personality disorder (SPD) is language abnormalities. The focus of this study was to determine whether or not there are also processing abnormalities of pure tones differing in pitch and duration in SPD. METHODS Thirteen neuroleptic-naïve male subjects met full criteria for SPD and were group-matched on age and parental socio-economic sta...

BACKGROUND Using the Kaufman Assessment Battery for Children (K-ABC) Conant et al. (1999) observed that visual and auditory working memory (WM) span were independent in both younger and older children from DR Congo, but related in older American children and in Lao children. The present study evaluated whether visual and auditory WM span were independent in Ugandan and Senegalese children. ME...

The heterogeneity of schizophrenia remains an obstacle for understanding its pathophysiology. Studies using a tone discrimination screening test to classify patients have found evidence for 2 subgroups having either a specific deficit in verbal working memory (WM) or deficits in both verbal and nonverbal memory. This study aimed to (a) replicate in larger samples differences between these subgr...

This study investigated whether cognitive measures obtained prior to cochlear implant surgery activation could predict improvements in spoken word recognition in adult cochlear implant recipients 6 months after activation. In addition to noncognitive factors identified by previous studies (i.e. younger age, shorter duration of hearing loss), the present results indicated that improvement in spo...

Decreased language lateralization is a well-replicated finding in psychotic patients. It is currently unclear, however, whether this abnormality is related to a particular symptom of psychosis or to psychosis in general. It has been argued that decreased language lateralization may be related to auditory verbal hallucinations. To elucidate this, these hallucinations should be studied in isolati...
