Prosodic knowledge affects the recognition of newly acquired words

An eye-tracking study examined the involvement of prosodic knowledge--specifically, the knowledge that monosyllabic words tend to have longer durations than the first syllables of polysyllabic words--in the recognition of newly learned words. Participants learned new spoken words (by associating them to novel shapes): bisyllables and onset-embedded monosyllabic competitors (e.g., baptoe and bap). In the learning phase, the duration of the ambiguous sequence (e.g., bap) was held constant. In the test phase, its duration was longer than, shorter than, or equal to its learning-phase duration. Listeners' fixations indicated that short syllables tended to be interpreted as the first syllables of the bisyllables, whereas long syllables generated more monosyllabic-word interpretations. Recognition of newly acquired words is influenced by prior prosodic knowledge and is therefore not determined solely on the basis of stored episodes of those words.     

The modulation of lexical competition by segment duration

In an eye-tracking study, we examined how fine-grained phonetic detail, such as segment duration, influences the lexical competition process during spoken word recognition. Dutch listeners’ eye movements to pictures of four objects were monitored as they heard sentences in which a stop-initial target word (e.g.,pijp “pipe”) was preceded by an [s]. The participants made more fixations to pictures of cluster-initial words (e.g.,spijker “nail”) when they heard a long [s] (mean duration, 103 msec) than when they heard a short [s] (mean duration, 73 msec). Conversely, the participants made more fixations to pictures of the stop-initial words when they heard a short [s] than when they heard a long [s]. Lexical competition between stop- and cluster-initial words, therefore, is modulated by segment duration differences of only 30 msec.     

Bias effects in facilitatory phonological priming

In four experiments, we examined the facilitation that occurs when spoken-word targets rhyme with preceding spoken primes. In Experiment 1, listeners' lexical decisions were faster to words following rhyming words (e.g., ramp-LAMP) than to words following unrelated primes (e.g., pink-LAMP). No facilitation was observed for nonword targets. Targets that almost rhymed with their primes (foils; e.g., bulk-SULSH) were included in Experiment 2; facilitation for rhyming targets was severely attenuated. Experiments 3 and 4 were single-word shadowing variants of the earlier experiments. There was facilitation for both rhyming words and nonwords; the presence of foils had no significant influence on the priming effect. A major component of the facilitation in lexical decision appears to be strategic: listeners are biased to say "yes" to targets that rhyme with their primes, unless foils discourage this strategy. The nonstrategic component of phonological facilitation may reflect speech perception processes that operate prior to lexical access.     

Rhyme decisions to spoken words and nonwords

Lexical effects in auditory rhyme-decision performance were examined in three experiments. Experiment 1 showed reliable lexical involvement: rhyme-monitoring responses to words were faster than rhyme-monitoring responses to nonwords; and decisions were faster in response to high-frequency as opposed to low-frequency words. Experiments 2 and 3 tested for lexical influences in the rejection of three types of nonrhyming item: words, nonwords with rhyming lexical neighbors (e.g.,jop after the cuerob), and nonwords with no rhyming lexical neighbor (e.g.,vop afterrob). Words were rejected more rapidly than nonwords, and there were reliable differences in the speed and accuracy of rejection of the two types of nonword. The advantage for words over nonwords was replicated for positive rhyme decisions. However, there were no differences in the speed of acceptance, as rhymes, of the two types of nonword. The implications of these results for interactive and autonomous models of spoken word recognition are discussed. It is concluded that the differences in rejection of nonrhyming nonwords are due to the operation of a guessing strategy.     

The Role of Regret in Medical Decision-making

In this paper, I explore the role that regret does and should play in medical decision-making. Specifically, I consider whether the possibility of a patient experiencing post-treatment regret is a good reason for a clinician to counsel against that treatment or to withhold it. Currently, the belief that a patient may experience post-treatment regret is sometimes taken as a sufficiently strong reason to withhold it, even when the patient makes an explicit, informed request. Relatedly, medical researchers and practitioners often understand a patient’s post-treatment regret to be a significant problem, one that reveals a mistake or flaw in the decision-making process. Contrary to these views, I argue that the possibility of post-treatment regret is not necessarily a good reason for withholding the treatment. This claim is justified by appealing to respect for patient autonomy. Furthermore, there are occasions when the very reference to post-treatment regret during medical decision-making is inappropriate. This, I suggest, is the case when the decision concerns a “personally transformative treatment”. This is a treatment that alters a person’s identity. Because the treatment is transformative, neither clinicians nor the patient him/herself can ascertain whether post-treatment regret will occur. Consequently, I suggest, what matters in determining whether to offer a personally transformative treatment is whether the patient has sufficiently good reasons for wanting the treatment at the time the decision is made. What does not matter is how the patient may subsequently be changed by undergoing the treatment.     

Predictors of perceived susceptibility of breast cancer and changes over time: a mixed modeling approach

OBJECTIVE: To examine predictors of perceived susceptibility to breast cancer and assess differences across three dependent measures. DESIGN: Annual surveys were completed by US women veterans (N = 3,758) participating in a repeat mammography intervention trial. Multivariable non-linear mixed model analyses examined individual- and group-level changes in perceived susceptibility to breast cancer. DEPENDENT MEASURES: Three single-item measures of perceived susceptibility to breast cancer (percent risk, ordinal risk, and comparative risk likelihood). Predictors included demographic, health status, health behavior, affect, knowledge, and subjective norm variables. RESULTS: Breast symptoms and greater cancer worry increased perceived susceptibility for all three measures. Other predictors varied by dependent measure. Random change, indicating individual variability, was observed for percent risk only. CONCLUSION: Despite small model effect sizes, breast symptoms and cancer worry were consistent predictors and may be good targets for messages designed to influence women's perceived susceptibility to breast cancer. Researchers may benefit from using measures of perceived susceptibility with larger response scales, but additional measurement research is needed. Combining indicators of perceived susceptibility may be undesirable when different predictors are associated with different measures.     

Complexity of referrals to a specialist psychotherapy service

Consecutive referrals to a specialist psychotherapy service were analysed for complexity. Some 71% had a severe enduring mental illness or personality disorder. Two-thirds of the rest had added psychosocial or behavioural complexity. Only 9% had no severe enduring mental illness, personality disorder, or added complexity; nearly half of these had somatoform disorder. Only 2% of the patients had uncomplicated depression or anxiety disorders.

Patients treated in this psychotherapy service are substantially different from those on whom NICE bases its guidance for the treatment of depression and anxiety, and for whom IAPT was conceived, it functions as a de facto complex case service.
