Within the context of psychological counsellors and therapeutic encounters of psychotherapists, clients may reveal illicit fantasies where it is unclear whether he or she is acting out his or her illicit fantasies. Using web-based survey methods to collect qualitative data, I explored therapists' decision-making when clients disclose illicit…

Pain assessments typically depend on self-report of the pain experience. Yet, in individuals with autism spectrum disorders, this can be an unreliable due to communication difficulties. Importantly, observations of behavioral hypo- and hyperresponsivity to pain suggest altered pain sensitivity in autism spectrum disorder. Neuroimaging may provide…

Memories relating to a painful, negative event are adaptive and can be stored for a lifetime to support preemptive avoidance, escape, or attack behavior. However, under unfavorable circumstances such memories can become overwhelmingly powerful. They may trigger excessively negative psychological states and uncontrollable avoidance of locations,…

Background: Behavioural interventions conceptualise self-injurious behaviour (SIB) as developing from early repetitive behaviours through acquisition of homeostatic functions in regulating stimulation and subsequent shaping into SIB through socially mediated or automatic operant reinforcement. Despite high success rates, such interventions rarely…

Background: In most individuals, injury results in activation of peripheral nociceptors (pain-sensing neurons of the peripheral nervous system) and amplification of central nervous system (CNS) pain pathways that serve as a disincentive to continue harmful behaviour; however, this may not be the case in some developmental disorders that cause…

Competing stimulus assessments (CSA) have been used to identify stimuli that are associated with reduced levels of problem behavior, presumably as a function of reinforcer competition. Following a standard CSA in which stimuli simply were made available, 2 more CSAs were conducted with additional components designed to enhance reinforcer…

Students with autism spectrum disorders (ASD) have difficulties with verbal language. Many interventions to remediate such deficits require numerous materials and significant teacher time. This study sought to determine if a simple multi-component intervention that incorporated noncontingent reinforcement (NCR) and verbal modeling would result in…

Pica is a potentially life-threatening behavior displayed by many individuals with developmental disabilities. In the present study, stimulus control procedures were examined during the treatment of pica exhibited by a 12-year-old boy with autism. First, the inhibitory effect of a treatment package was tested. Next, neutral stimuli (i.e.,…

In this study, the side effects of contingent shock (CS) treatment were addressed with a group of nine individuals, who showed severe forms of self-injurious behavior (SIB) and aggressive behavior. Side effects were assigned to one of the following four behavior categories; (a) positive verbal and nonverbal utterances, (b) negative verbal and…

A functional analysis was performed on a five-year-old nonverbal Autistic female with severe self-injurious behaviors. The self-injurious behaviors (hand-to-head, hand-to-jaw, hand-to-face) and loud vocalizations were targeted. Two types of sessions, enriched environment and instructor controlled preferred stimuli, were alternated throughout the…

In this case study, interactions were examined between features of Rett syndrome and operant conditioning as determinants of self-injurious behavior (SIB). Analysis suggested different functions for two forms of SIB: automatic reinforcement by sensory stimulation and escape from social interactions. Features of Rett syndrome tended to maximize the…
