Improving session attendance in mental health and substance abuse settings: a review of controlled studies

Patient nonattendance to scheduled sessions results in excessive costs to mental health and substance abuse providers and compromises the care of clients. This paper presents a comprehensive review of interventions that have been shown to increase session attendance rates in these settings. Unique to other review papers, reliability estimates were performed in the selection and evaluation of obtained studies. Reliability of article selection and evaluation strategies was excellent (.80 to .88). Study results indicate several attendance improvement methods appear to be particularly promising, such as scheduling appointments promptly, reminder letters and telephone calls, soliciting patient commitment, and helping to resolve obstacles to attending the session. The specific manner in which these interventions are implemented appears to influence session attendance rates. Moreover, some attendance improvement interventions are clearly effective in some settings, but not others. Specific recommendations are provided in light of the study findings.     

Making choices impairs subsequent self-control: a limited-resource account of decision making, self-regulation, and active initiative

The current research tested the hypothesis that making many choices impairs subsequent self-control. Drawing from a limited-resource model of self-regulation and executive function, the authors hypothesized that decision making depletes the same resource used for self-control and active responding. In 4 laboratory studies, some participants made choices among consumer goods or college course options, whereas others thought about the same options without making choices. Making choices led to reduced self-control (i.e., less physical stamina, reduced persistence in the face of failure, more procrastination, and less quality and quantity of arithmetic calculations). A field study then found that reduced self-control was predicted by shoppers' self-reported degree of previous active decision making. Further studies suggested that choosing is more depleting than merely deliberating and forming preferences about options and more depleting than implementing choices made by someone else and that anticipating the choice task as enjoyable can reduce the depleting effect for the first choices but not for many choices.     

Source memory for unrecognized items: Predictions from multivariate signal detection theory

We report three experiments investigating source memory for words that were called "new" on a recognition test. In each experiment, participants could accurately specify the source of words that they failed to recognize. Results also demonstrated that source memory for unrecognized items varied with the bias to respond "old" in recognition decisions: Participants displayed unrecognized source memory when they were told that 25% of the recognition test words were old (promoting conservative responding) but not when they were told that 75% of the test words were old (promoting liberal responding). Our results were successfully predicted by a multivariate signal detection approach to recognition/source memory.     

Agrammatism in sentence production without comprehension deficits: reduced availability of syntactic structures and/or of grammatical morphemes? A case study

A French-speaking patient with Broca's aphasia--following a left-hemisphere lesion involving the sylvian region but sparing Broca's area--is presented. Like G. Miceli, A. Mazzuchi, L. Menn, and H. Goodglass's (1983, Brain and Language, 19, 65-97) case 2, this patient produces agrammatic speech in the absence of any comprehension deficit. Unlike Miceli's patient, though, agrammatic speech can be observed in all sentence production tasks (from spontaneous speech to repetition, oral reading, and writing) whereas production of individual words--be they open class or closed class--is almost always intact. On the basis of extensive (psycho)linguistic testing, it is argued that this patient's deficit is not central and not crucially syntactic (at least) at the level of knowledge but seems to disrupt specifically those (automatic?) processes responsible for both retrieval and production of free-standing grammatical morphemes whenever they have to be inserted into phrases and sentences.     

THERE ARE TWO WORD-LENGTH EFFECTS IN VERBAL SHORT-TERM MEMORY:

Abstract— In the word-length effect (WLE), lists of shorter words are better recalled than lists of longer words This effect a fundamental to decay-based theories of verbal short-term memory, such as the phonological loop theory (Baddeley, 1986) The WLE has been attributed to the time taken to articulate words, not their structure, a critical point in the debate between decay and interference theories However, this article, we show that the traditional WLE comprises two opposed effects an advantage for words spoken more quickly (short words in terms of duration) and an advantage for words with more elements (long words in terms of complexity) We also report two interactions a disadvantage for a midlist change in duration and an advantage for a midlist change in complexity These results contradict simple decay- based theories and establish the importance of interference in short- term memory We discuss whether decay is also required
