Marks has promoted the use of cognitive behaviour therapy as an effective clinical approach to smoking cessation. This research began in New Zealand where Paul Sulzberger and he developed the Isis Smoking Cessation Programme (Sulzberger & Marks, 1977). After returning to England in 1986 Marks developed a UK-version of the programme which was originally published by the British Psychological Society

 and mental imagery led to the development of the Vividness of Visual Imagery Questionnaire (VVIQ)
Vividness of Visual Imagery Questionnaire (VVIQ)
The Vividness of Visual Imagery Questionnaire was published in 1973 by the British psychologist David Marks . The VVIQ consists of 16 items in four groups of 4 items in which the participant is invited to consider the image formed in thinking about a specific scenes and situations. The vividness...

, a tool for the assessment of individual differences in visual imagery. Marks (1973) reported that high vividness scores correlate with the accuracy of recall of coloured photographs. In 1995 he published a new version of the VVIQ, the VVIQ2. This questionnaire consists of twice the number of items and reverses the rating scale so that higher scores reflect higher vividness. Rodway, Gillies and Schepman (2006) found that high vividness participants were significantly more accurate at detecting salient changes to pictures compared to low vividness participants, replicating an earlier study by Gur and Hilgard (1975). Recently Cui et al. (2007) found that reported image vividness correlates with increased activity in the visual cortex. This study shows that the subjective experience of forming a mental image is reflected by increased visual cortical activity.

Literacy and IQ

Marks (2010) published a new explanation of why IQ scores systematically vary across time, race and nationality. Marks (2010) hypothesizes that IQ differences across time, race and nationality are all caused by differences in literacy. Intelligence test performance requires literacy skills not present in all people to the same extent. In eight different analyses mean full scale IQ and literacy scores yielded correlations ranging from .79 to .99. Racial differences in IQ and the Flynn effect
Flynn effect
The Flynn effect is the name given to a substantial and long-sustained increase in intelligence test scores measured in many parts of the world. When intelligence quotient tests are initially standardized using a sample of test-takers, by convention the average of the test results is set to 100...

both have a similar explanation: literacy differences across race and across time could be the cause of both. Racial IQ differences are converging as the literacy skills within two populations become more equal. Thus racial differences have an environmental cause, just like the Flynn effect.
